Dr. Memory internal crash

[Chris Carter]

I have a segfault I need to find, but Dr. Memory seems to have caught a similar bug. My program is compiled in MinGW 32-bit. I get the dialog in the attached image, followed by Notepad with this text:

Dr. Memory version 1.8.0 build 8 built on Sep  9 2014 16:27:02

Dr. Memory results for pid 7812: "Omni.exe"

Application cmdline: "Omni.exe"

Recorded 108 suppression(s) from default C:\Program Files (x86)\Dr. Memory\bin\suppress-default.txt

Here's console output:

~~Dr.M~~ Dr. Memory version 1.8.0

When I try it with the same program compiled in MSVC 32-bit, I get this in console:

ERROR: failed to create process for "C:\Users\Chris\Code\build-Omni-Desktop_msvc2013_32bit_no_Qt-Debug\Omni.exe":

<press enter to dismiss>

The "failed to create process" sounds like there's something wrong with the path or permissions.

For the MinGW, please try the standard debugging steps listed at http://code.google.com/p/drmemory/wiki/Debugging.  If you can supply the program, or a memory dump (see the wiki page for how to create one in windbg), we may be able to diagnose and fix it.  Please file an issue in our tracker about this crash.

(I resolved the issue I was trying to use Dr. Memory for, and the crash persists. Compilation with MSVC now crashes the same as with MinGW.)

Want what you have,
Chris

We suspect that recent issues with Windows 8.1 are all due to the massive, optional update KB3000850 which was pushed out on Nov 18.  Things work fine on Windows 8.1 without that update.  We are investigating the update.
