--- Comment #10 from Kostya Serebryany <kcc at gcc dot gnu.org> --- Your stack traces tells me this: __sanitizer::MmapOrDie calls strerror, which means that mmap call failed. This may happen if the process OOM-ed (unlikely in your case), or may have some kind of limit (also unlikely, because the process managed to allocate the asan shadow). Let's try two things: 1. run with ASAN_OPTIONS=verbosity=1 and send us the log file 2. run under strace and figure out why did the last mmap fail
