Segmentation Fault on running program

Hi, how are you?

I cannot run synfigstudio on a fresh install.
The splashscreen progress bar loads almost to the end then it suddenly closes.
Please I'd like to ask you for help or advice.

when I run gdb synfigstudio
(synfigstudio:1651): Gtk-WARNING **: new: missing action new
(synfigstudio:1651): Gtk-WARNING **: open: missing action open

Program received signal SIGSEGV, Segmentation fault.

uname -a returns

System is up to date.
There are attached to this message:
gdb_log.txt output of gdb synfigstudio
pkg_info.txt output of pkg version
portmaster_info.txt output of portmaster -l

If there is any further info I missed I'd be glad to provide.

Thanks a lot.
Rafael, are you installing from a package or from a port. If it's from a port, what I'm going to propose is a very very long shot. But first, you have to be absolutely sure that all your ports are up to date. Odd things happen if not. I'm more a if-it-aint-broke personality, but that's not compatible with FreeBSD. So, to find out if any port needs an upgrade, I use:
portsnap fetch update then portmaster -L | grep New | sort

All ports in the ports tree are supposed to work because they would be purged otherwise. If they don't work, chances are that it's a small detail that has been overlooked. I had a segmentation fault on a fresh install of news/pan last week, and got it fixed with a compilation tip from a different forum topic here, but a few years back. Here goes:
  1. Go to the port directory
  2. Open the Makefile file (also make a copy of it to cancel any change made)
  3. Add -static-libgcc -static-libstdc++ to the end of the LDFLAGS+= line.
  4. make deinstall
  5. make clean
  6. make
  7. and if no error: make reinstall

I was lucky! Maybe you will be too!

Corresponding PR 208763 was created 2 months ago (2016-04-13). The fix is simple, well known and tested. But somehow still is not submitted. BTW the same fix for the previous version of pan took around 9 months to get submitted to the ports tree.
