segfault after recompile

[birdspider]

Someone got an idea why it would stop working after a recompile ?

The only way to know would be to recompile it with -O0 -g and see the crash with debug symbols.

[birdspider]

CFLAGS=-march=native -O2 -pipe -fno-plt -fexceptions -Wp,-D_FORTIFY_SOURCE=2,-D_GLIBCXX_ASSERTIONS \
   -Wformat -Werror=format-security -fstack-clash-protection -fcf-protection \
   -g -fvar-tracking-assignments \
   -fdebug-prefix-map=/home/birdspider/.cache/pacaur/noise-suppression-for-voice/src=/usr/src/debug \
   -O0

(those are a mix of Archlinux defaults CFLAGs + debug + -O0)

EDIT: I just now realize its an SIGABRT, not an SIGSEGV - I don't know if it makes a difference

Thanks, I think I see slightly suspicious code.
