  "message": "[Frontend/Offloading] Fix use-after-reallocation in sycl::writeSymbolTable (#197612)\n\n`writeSymbolTable` took raw pointers into the `SmallString` buffer\n(`Header`, `Entries`) and then called `Out.append()` / `Out.push_back()`\ninside the loop to write string data. When the `SmallString` needed to\ngrow, it reallocated, silently invalidating those pointers. All writes\n  through `Entries[I]` after the first reallocation were undefined\nbehaviour; UBSAN caught this as a crash (exit code -6 / SIGABRT) on the\n  sanitizer-x86_64-linux-bootstrap-ubsan builder.\n\n  The fix pre-computes the total buffer size (header + entry array +\n  all null-terminated name strings) and calls `reserve()` before any\n  pointers are taken, guaranteeing that the subsequent `append` and\n  `push_back` calls cannot trigger a reallocation.",
