Just as planned ;)

Looks OK to me, as '-g' is there.

Hm... I'm not familiar with Geany at all. It *may* be a way to tell you
that Geany is unable to launch gdb (which should have been installed
along the way). It may mean anything else of course.

Are usual signs of bad programming, this time at Geany side. These messages tell
that they try to free certain variables of type GString, but don't even
both try to check beforehand if said variable contain something.
What we see here is just a bunch unhandled assertions. By itself it may
mean anything.

Beats me, sorry. I'd start the troubleshooting of this by attaching with
strace(1) to Geany's process - just to ensure whenever Geany is
actually tries to launch gdb.
