Doesn't output converted exe

I installed cv2pdb with the VisualD installer, but anytime I try to use it it does create a pdb, however, no new exe is created and the existing exe is left unchanged (and there's no error message or any other stdout/stderr output). I've checked everything over at ( http://www.dsource.org/projects/cv2pdb/wiki/Installation ) and it all looks good.

The exe's I try to convert have been compiled with "-g". I've also tried "-gc". But nothing seems to work.

Any ideas?

Sounds strange. Does it work within Visual D?

Maybe there is an access problem to the executable because it is still opened by another process. Have you tried the command line with 3 arguments?

It doesn't work within VisualD either.

I checked and the exe was not being used by any other process.

Using 3 args still gives me the same result.

Hmmm, does cv2pdb output its banner and version if you start it without parameters?

What OS are you running. It might not work with anything before XP, though I only have found evidence that it will definitely not run with something before win2000.

Can you create a trace file with procmon.exe from the sysinternal suite ( http://technet.microsoft.com/en-us/sysinternals/bb842062 )?

Sorry it took until now to get to it. Here's the pml file:

From the log file, I can see a termination code of 0xC0000005, which means that there is a memory access violation happening. Can you provide the dax_debug.exe to reproduce here? Does it also happen if you just convert a "hello world" program?

Sigh. It's again a crash due to very long symbol names. This time, a compressed name (97 characters) is expanded to more than 4096 characters (starting with "_D3dmd2Id2902__T5idgenTS3dmd2Id2IDTS3dmd"). I just cut it off now.

Please try the new version 0.22 from the download folder.

I haven't had a change to actually try it in VisualD with the debugger yet, but that new version does seems to work so far, thanks. A pdb is created, the exe is modified (and shrunk to roughly the size of it's release build, with the pdb's size approximately the difference in the two sizes), and the newly modified exe still runs.
