Hi,
I'm having a problem runing MinGW gdb in xemacs in that gdb doesn't show
source code when debugging in xemacs. After start, I do a step but the
xemacs editor shows two windows: top for commands of a debugger and bottom,
which is empty. I am using MinGW gdb 6.8 distributed on the MinGW website
http://sourceforge.net/project/showfiles.php?group_id=2435&package_id=20507
Below is an output of the MinGW gdb:

PS
I had to switch to the MinGW gdb since the Cygwin gdb couldn't debug
this program I'm running but the MinGW gdb could. The cygwin gdb gave
this error and exit:
Program received signal SIGTRAP, Trace/breakpoint trap.
0x7c901231 in ntdll!DbgUiConnectToDbg () from C:\WINDOWS\system32\ntdll.dll
(gdb) warning: HEAP[osglightd.exe]:
