FindThreads: Add pthread_cancel to program to test for pthreads in libc (!4056) · Merge requests · CMake / CMake

Cristian Morales Vega requested to merge RedDwarf/cmake:findthreads_tsan into master Nov 15, 2019

When using ThreadSanitizer our existing CMAKE_HAVE_LIBC_PTHREAD test program links using symbols from the tsan library. Among the symbols not provided by that library, pthread_cancel() seems to be the less risky symbol to add to the check.

Fixes: #19981 (closed)
