I had same problem. On x64 linux machine worked fine, on x86 windows in release mode worked fine but sometimes couldnt start. In debug mode program refused to execute with same problems:
> Invalid parameter passed to C runtime function. In my case it was problems with stack. Try to move your objects to heap and catch exeptions on memory allocations. Wed, 13 Jun 2012 16:25:59 -0400 от Josiah Bryan <josiahbr...@gmail.com>: I'm attempting to debug an odd problem wherein my program (http://code.google.com/p/dviz/) crashes when displaying certain UTF-8 strings. That's not really why I'm emailing - the problem I'd like your help with is that I'm unable to run the program in "Debug" mode in Qt Creator on Windows 7. I've set the project in Qt Creator to the "Debug" build and tried to run it in the Debugger (F5). The program builds and launches - however, before the main UI can appear, an error dialog titled "Microsoft Visual C++ Runtime Library" appears giving the following error: "This application has requested the Runtime to terminate in an unusual way. Please contact the application's support team for more information." Below the console output from Qt Creator. As you can guess, it does run correctly in "Release" mode in Qt Creator (just crashes when the user performs a certain UI action - hence why I want to run it in Debug mode. Note that it does not crash on linux in gdb or in release mode - so this is specific to Windows and the debugger in Qt Creator.) You'll note there are comments in the console output below regarding constructing QApplication before QPaintDevice and other references to QApplication - well, I don't know why it's complaining about that, because QApplication is created on the second line of code to be executed in in main() - see http://code.google.com/p/dviz/source/browse/trunk/src/main.cpp#36 for proof. In short, I can't run in the Debugger to trace the crash in Release, because the debugger crashes before the program even starts. (And the debugger doeesn't give a stack trace to indicate where the MSVC runtime freaks out at.) Any thoughts on what I can do to fix this or at least track down the problem more accurately so I can get the program to execute in the debugger?
