Hi,

AFAIK,  libgcc_s_dw2-1.dll is statically linked so it is irrelevant the origin of the file.

I have experienced the same crashes and I can confirm two things:
- No crashes with gcc v3.x.x
- No crashes with gcc v4.5 sjlj

And this thread might confirm the last point.

Now I am going to build with tdm-gcc-4.7.1-2 MinGW sjlj, and test stability. If anyone would like to test my binaries, please, let me know: I will be pleased.

HTH

Miguel.
