This is a bug in gdb, so we can not fix it on our end.

But a couple of notes that may help.

1) You can turn of the debug hint somewhere in the options (codetools) IIRC

2) Try compiling with dwarf or stabs (project options / debugging). I 
think the default is stabs, so you should try dwarf.

BUT: You need to apply that to all packages too (each package has an 
option). Easiest way to do this is "Additions and Overrides"

3) Try a different version of GDB.
I have not tested this on Linux, but on win only. But it may be similar 
on Linux.
My observation is that gdb at version 7.7 and above crashes more often 
(and especially with stabs).
