Is that gtk+ built with the egcs-bug workaround? (the test is to run the
'gtk/testgtk' program that is built along with the libraries, and choose the
'clist' option: it will crash without the workaround). There's a bug in egcs
in which functions with a large number of arguments (maybe 8 or 9?) compiled
with -fPIC -O2 will crash. Compiling such files -O1 is OK. The only files I've
ever seen trigger this bug are in gtk+. I reported the bug to the egcs folks
last year and it's in the testsuite (980523-1.c), but as of 2 weeks ago it had
not yet been fixed.

The workaround for gtk+ is to build with something like this:

 CFLAGS=-O2 ./configure
 cd gtk; make CFLAGS=-O1 gtkclist.lo gtkctree.lo; cd ..
 make

This may be a problem for a while.. if egcs hasn't been fixed by now, I
suspect the bug must be pretty tough.

You can also build that testgtk after the fact to test for the problem:
 tar xzf gtk+-1.2.0.tar.gz
 cd gtk+-1.2.0/gtk
 gcc -o testgtk `gtk-config --cflags` testgtk.c `gtk-config --libs`
 ./testgtk
 [hit "clist"]
