Thanks for the reply. I already had logging enabled:

All files have the -g flag, which makes sense, because I can inspect a variable if I set a watch on it, and set breakpoints anywhere. The problem is that I cannot single step.
Here is the debugger log output - I started the program and it ran to a breakpoint I had set. Then I tried twice to single step (Next Line - F7), and both times I received the Acessing Memory Error:

I can follow some of that, but not all. Looking at the error:
C:\WINDOWS\SysWOW64\ntdll32.dll: No such file or directory
I verified that that file is not on my system (64-bit XP) - could that be the problem? I have an ntdll.dll in my Windows/system32 folder, but no ntdll32.dll anywhere.

From http://cygwin.com/ml/cygwin/2007-10/msg00179.html
--- Quote ---Simply copying ntdll.dll to ntdll32.dll in SysWOW64 seems to make gdb "happy",
i.e., it no longer displays the message. Gdb seems to incorrectly "determine"
that the name of the .dll should have "32" appended to it. That may be
correct for other .dlls, but not this one.

Use at your own risk; the above is just goggle info. I have no idea if it is right; but, it makes sense.

Can you post the top of the debugger's log?
The lines with the version info?
p.s. please use code tags for long/any pastes... (if you have the time edit your post, so it utilizes them)

Sorry about the code tags - I'd been looking for something to use and missed that, ended up using teletype instead...
Here's the entire log from startup to the breakpoint and then two attempts to single step:

from the error:

it seems the path:
C:\WINDOWS\SysWOW64\ was not in PATH environment variable.
And you could try a recent mingw gcc and gdb (gcc 4.5.3 snapshot, gdb 2011xxx), see here:
http://pcxprj.googlecode.com/files/MinGW_win32_gcc4.5.3static_snapshots.7z
To test it whether the bug was fixed. :D
