I know that equation.com makes it simple to use GCC - on the other hand, 
I do recall that I once tried to trace a reported internal-compiler 
error (segfault), which turned out occur only with the equation.com 
build but not with the builds of the MinGW-w64 project.

Hence, you could try another build  - e.g. those from MinGW-w64 project 
itself. (Admittedly, their download website is not very well 
structured.) The best build I found browsing their site is: 
http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/rubenvb/gcc-4.8-release/
