--- Comment #9 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> --- (In reply to Jakub Jelinek from comment #8) > No. libsanitizer is only supported on selected *-*-linux* targets, and > (apparently prematurely so) on x86_64-*-darwin* and i?86-*-darwin*. Fair enough, I didn't realize that. For a long time, libsanitizer broke bootstrap on darwin so I was used to build without it. An option is to have a recent llvm-symbolizer in one's PATH while running the testsuite. This brings the number of failures (make check-gcc RUNTESTFLAGS="asan.exp") down from 60 to 36. (I will investigate the remaining failures separately.)
