Each of them pushes\nback the provided pointers into a separate array, `Modules` and\n`ModulePCTable` respectively. These arrays are meant to be kept in-sync;\nindex i into Modules should refer to the same `.so` as index i into\nModulePCTable. The assertion was triggering because these lists got\nout-of-sync.\n\nThe problem is that the 8bit handler contains this line:\n```\nif (Start \u003d\u003d Stop) return;\n```\nbut the PC handler contains no such corresponding line. This meant that\nif a module was ever instrumented but “empty” (its 8bit counter and PC\narrays were both of length 0), then its PC array would still be added\nbut its 8bit counter array would not.\n\n# Why this issue was never seen before\n\nThe circumstances to trigger this issue are unusual:\n- You need a compilation unit that doesn\u0027t contain any code (though it\nmay contain global variable declarations and similar). That doesn\u0027t\nhappen very often.\n- That compilation unit must be dynamically linked, not statically\nlinked. If statically linked, it’ll be merged into a single “module”\nwith the main binary, and the arrays will be merged as well; you won’t\nend up with length-0 arrays.\n- To notice the issue, assertions must be enabled. If disabled,\nlibFuzzer will be buggy (it may have worse coverage), but it won\u0027t\ncrash, and \"worse coverage\" is extremely unlikely to be noticed.\n\n# This change\n\nThis change solves the issue by adding the same `if (Start \u003d\u003d Stop)\nreturn;` check to `HandlePCsInit`. This prevents the arrays from getting\nout-of-sync. This change also adds a test that identifies the previous\nissue when compiled with assertions enabled, but now passes with the\nfix.\n\nGitOrigin-RevId: 3f52e97df77a0c84ffe61f3148ef9b1a18a67f69\n" }, { "commit": "41790b73ecedf5d0609f10a5d8924e56430ee4fb", "tree": "7fb9d01faee4b8f36c6a47ec94380ac8e1af10a1", "parents": [ "086c70cfdf94600b5a3fe1b40169f5e51058ebde" ], "author": { "name": "Amit Kumar Pandey", "email": "pandey.kumaramit2023@gmail.com", "time": "Tue Sep 16 23:41:20 2025 +0530" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Tue Sep 16 11:13:28 2025 -0700" }, "message": "Reapply \"[NFC] Fix CodeQL violations in compiler-rt.

The\nmain thread is frozen because it\u0027s waiting to suspend either the alarm\nor rss thread which is stuck waiting for an exception they sent out to\nbe handled. Specifically, both threads send out a synthetic\n`ZX_EXCP_THREAD_STARTING` exception to be handled by the crash handling\nthread which sets up an exception channel on the whole process with\n`ZX_EXCEPTION_CHANNEL_DEBUGGER`. This is the only channel type that\nlistens to thread stop/start exceptions. Normally, the exception would\nbe ignored and the alarm or rss thread would continue normally once the\ncrash handling thread closes the read exception. However, the memory\nsnapshot machinery can suspend this thread while its in the process of\nwaiting for or handling a `ZX_EXCP_THREAD_STARTING` sent by either the\nrss or alarm thread. If this is suspended first, then we attempt to\nsuspend either the alarm or rss thread while they\u0027re still waiting for\nthe crash handling thread to handle its exception, we will freeze\nwaiting for those threads to give the suspend signal, which they won\u0027t\nbecause they\u0027re blocked on waiting for the exception handler. This is\nthe deadlock.\n\nUntil there\u0027s a way for the memory snapshot machinery to suspend the\nthread while it\u0027s stuck on an exception, then we can work around this in\nthe meantime by just ensuring the alarm and rss threads start normally\nvia signals on the initial startup path. I can assert locally the\nfreezing doesn\u0027t occur after 6000 runs where prior we would see it every\ncouple hundred runs. Note this type of issue can arise again if the\nfuzzing test launches any dangling threads that happen to not start yet.\nOne of the recommendations for writing a fuzz test is that the test may\nlaunch threads, but they should be joined by the end of the test\n(https://llvm.org/docs/LibFuzzer.html#fuzz-target), so hopefully we\nwon\u0027t see this type of bug rise frequently from fuzz tests. More\nbroadly, this can also arise if any process launches its own debugger\nvia `ZX_EXCEPTION_CHANNEL_DEBUGGER`, but I would think in practice this\nisn\u0027t very likely to happen.\n\nMore context in https://fxbug.dev/436923423.\n\n---------\n\nCo-authored-by: Petr Hosek \u003cphosek@google.com\u003e\nGitOrigin-RevId: b9987503d2ed2768ff8b64446049383412c7806b\n" }, { "commit": "e815906e1f4736cf370bcc33bd5f2a503c28e81f", "tree": "8d078edef6ed5118e28153bde91199610f216a3b", "parents": [ "7080db937e4e3ed710f44c41cc99a6f6ad934c5b" ], "author": { "name": "Keith Randall", "email": "keithr@alum.mit.edu", "time": "Tue Aug 12 08:52:58 2025 -0700" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Tue Aug 12 08:54:45 2025 -0700" }, "message": "Revert \"[libFuzzer] always install signal handler with SA_ONSTACK\" (#153114)\n\nReverts llvm/llvm-project#147422\n\nSeems to be causing problems with tracebacks.
