--- Comment #9 from Martin Liška <marxin at gcc dot gnu.org> --- (In reply to dominik.strasser from comment #5) > ASAN from git crashes like this. Looks like a double fault. Yes, SEGFAULT happens right in the sanitizer code that's responsible for creation of a thread. Thus I suspect some incompatibility with glibc. > SignalHandler_Unix.h is in my application's code. > I've attached ASAN's debug output where I removed all messages talking about > poisoning/unpoisoning as they look unrelated.
