Trouble in MinGW Land

I updated from CVS last night and attempted to build XEmacs. It did ok until it started trying to run temacs.exe. Then it would give an error dialog gox and exit. It still tried to dump xemacs.exe, but failed because xemacs.exe was too small. In an effort to figure out what was happening, I ran gdb on one of the temacs calls. What I found was that everything seemed to work fine until memory_warnings() called start_of_data(). At that point a console window poped up and disappeared, then gdb reported that it had NO STACK. Any ideas on what is going on? (This is the mingw build of XEmacs on a Win98 machine.) Craig P.S. The version of gdb that comes with the Cygnus stuff is really cool.
