Summary: Without this diff, the test segfaults. Examining the generated executable (which gets auto-deleted likely by cmake/ninja) yields this error message: ThreadSanitizer failed to allocate 0x4000 (16384) bytes at address 1755558480000 (errno: 12) Note that the address has more than 47 bits, which on amd64 means special treatment and therefore points out an overflow. The allocation came from __tsan_map_shadow on a .data pointer, which (on my work Debian-based box) means the 0x550000000000 range. This doesn't correspond to the constants mentioned in tsan_platform.h for Go binaries on Linux/amd64. The diff therefore allocates memory in the sort of area Go programs would, and prevents the test from crashing. It would be nice if reviewers kindly considered other setups and architectures :-) Reviewers: kcc, dvyukov Subscribers: kubamracek, delcypher, #sanitizers, llvm-commits Differential Revision: https://reviews.llvm.org/D44071 llvm-svn: 327621 |
