gcc is either 5.3.0 or 7.1.0.
this manifests also with scribus 1.5.3 but *NOT* with 1.5.2 (that works fine)

This crash occurs in code generated by compiler at exit of a function which has basically no reason to crash. Might be a compiler bug. I do not see such crash on Windows using Visual C++ compiler.

hey jghali, good catch!

I just tried to build 1.5.3 and the latest svn using clang-4.0.1 (sorry I didn't think about it earlier) and they didn't segfault at launch! :)

as using an alternative compiler is perfectly acceptable (both are installed by default on Slackware), packaging on Slackware of the development version, IMHO, is OK.

I've tested latest trunk revision on Ubuntu 17.04 (gcc 6.3) and OpenSuse Leap 42.2 (gcc 4.8.5). No crash either. So it really looks like a bug on Slackware gcc.
