mixing cout with gtk

[Scott Dattalo <scott dattalo com>]

Has suddenly produced core dumps for me.

I've been using gtk for a few years now, but I'm stumped on this one. Perhaps
somebody's seen this too and can help out. It appears that I'm unable to write
to the cout stream. However, if I configure my program without the gui (there's
a command line version too), the cout's work fine ?!?

Why all of a sudden? Well I upgraded from gtk 1.0.? to 1.2.8 and that's when I
noticed the problems. I've done many `experiments' with my system... but suffice
it to say that I'm now running gtk/glib 1.2.6 . I've attempted to remove all
traces of old gtk/glib libraries and I'm fairly sure I've gotten them all. The
1.2.6 version of glib/gtk were installed from RPMs. I've also installed the
`devel' versions of gtk/glib. 

I use automake - is there a check that's possibly being missed?

My system is basically a RH6.0 system with numerous upgrades. My gcc is old:
$ gcc --version
egcs-2.91.66


(BTW, my project is gpsim, http://www.dattalo.com/gnupic/gpsim.html , a
simulator for pic microcontrollers.)

Here's a snip of my `main.cc'.

------------------------

void
main (int argc, char *argv[])
{

  cout << "this is a test with cout\n";

------------------------

And here's the backtrace after it dumps core

Any ideas?
