Unfortunately, the gtest infrastructure can allocate\na pointer that happens to be the previously freed pointer. Thus the free\ndoesn\u0027t fail since the spawned process does not attempt to free all of\nthe pointers allocated in the original test.\n\nNOTE: Scudo should be checked to make sure that the TSD is not always\nreturning pointers in the same order they are freed. Although this\nappears to be a problem with a program that only does a small number of\nallocations.\nGitOrigin-RevId: 309bb1ed6844a5936158a2a8406d1b77bda37b94\n" }, { "commit": "8ee815453579cc9f0c7e35f4f89c7a2182066ee1", "tree": "ca9901a254a9eba4f975c4839b7dacc285b15f7d", "parents": [ "8695ad12b793f9a832bef986ac77670a4612e64c" ], "author": { "name": "ChiaHungDuan", "email": "chiahungduan@google.com", "time": "Wed Jul 09 13:42:02 2025 -0700" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Wed Jul 09 13:43:13 2025 -0700" }, "message": "[scudo] Move out the definitions of member functions in primary allocators (#147601)\n\nThis greatly improves the readability so that we are able to tell the\ndesign by the concise class definition.\n\nGitOrigin-RevId: 4ea0ef2e944762c67395de080f1bc6fe06a0c66b\n" }, { "commit": "8695ad12b793f9a832bef986ac77670a4612e64c", "tree": "46ca239296cd14f1cee02b72c3eae48bbc0b70c1", "parents": [ "dbc816cc772a5cfe0acfd7789c1e054d14716f00" ], "author": { "name": "ChiaHungDuan", "email": "chiahungduan@google.com", "time": "Tue Jul 08 11:07:05 2025 -0700" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Tue Jul 08 11:10:58 2025 -0700" }, "message": "[scudo] Make block storage in TransferBatch trailing objects (#144204)\n\nThis allows us to change the number of blocks stored according to the\nsize of BatchClass.\n\nAlso change the name `TransferBatch` to `Batch` given that it\u0027s never\nthe unit of transferring blocks.\n\nGitOrigin-RevId: 8b65c9d1ed298a9f4be675d1da9d678fd61ff2b0\n" }, { "commit": "dbc816cc772a5cfe0acfd7789c1e054d14716f00", "tree": "e91272e22d3f802464f7d46d951b5820919e8243", "parents": [ "f347c350d53ea4004879308ef2f368f29629cad1" ], "author": { "name": "Christopher Ferris", "email": "cferris1000@users.noreply.github.com", "time": "Wed Jun 18 09:12:53 2025 -0700" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Wed Jun 18 09:15:47 2025 -0700" }, "message": "[scudo] Make report pointers const.
