Hello World? –karlphillip Mar 29 '12 at 20:24 1 no.why is it important?i have a makefile for it .and it works ok on win7. –Yakov Mar 29 '12 at 20:29 If it wasn't important I wouldn't be asking it. I'm trying to determine if this is a random problem, or if it's something that happens consistently, and if its something that is reproducible with the smallest possible application. Are you telling me that compiling a Hello World application doesn't trigger this error? Have you tested this? –karlphillip Mar 29 '12 at 20:38 1 it doesnt work for any app.also restart doesnt help –Yakov Mar 29 '12 at 21:07 add a comment| 4 Answers 4 active oldest votes up vote 7 down vote accepted Reboot your system: Most users complaining about this problem reported it goes away after a reboot. If you are using Windows 7, check the message from BerndP in this thread, it has some tips related to adjusting Virtual Memory settings on Windows. Might be some software interfering with Cygwin: This post brings an interesting discussion of random pro

It works fine without the arrays (simulation size ~2MB), but as soon as you use even the smaller arrays (that worked with cygwin) it fails. The error message (the same one as above "unknown software exception (0xc00000fd)") pops up immediatly, the process doesn't seem to "collect" memory. When compiling with MSVC I get the warning about a too large image size of 4xxMB, or so. I am also trying to avoid MSVC because I need to change the program (add additional h-files,...) when using MSVC. Another interesting thing I noticed is that the simulation runs faster
