For reference: https://sourceware.org/git/?p=glibc.git;a=blob;f=nptl/pthread_cancel.c;hb=HEAD#l38 When the glibc is generated as a dynamic library, pthread_cancel call the pthread_cancel_init() function. https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/nptl/unwind-forcedunwind.c;hb=HEAD#l53 This function try to load libgcc_s by doing a dlopen. It looks like it's working in some distributions without haproxy being linked to libgcc_s or libpthread linked to libgcc_s, but I didn't find any explicit fix for that. -- William Lallemand
