Look like a double free inside gtk css module.

i've just manually compiled font-manager from source myself (i.e. without using xbps-src), and it runs fine. Building via xbps-src, however, produces a binary that segfaults. What things in the xbps-src build environment might i be able to try changing?

Most of time, it's -fstack-clash-protection -D_FORTIFY_SOURCE=2

@sgn: Thanks, i wondered if that might be it .... But no, commenting out the relevant CFLAGS lines in hardening.sh makes no difference.

I think this issue has been fixed in some release.
