[racket-dev] Seg fault

After some experience with Visual Studio 2010 Express I have a result.
Before crash debugger notifies about some unhandled 0xC0000005 exceptions:

Unhandled exception in the "0x65364ac8" in "DrRacket.exe": 0xC0000005:
Access violation when writing "0x049a3fbc"

Those exceptions are the same.

The corresponding stack trace:

libpixman-1-0.dll! 65364ac8 ()
