Mingw (g++) will statically link its own C++ runtime. DLLs compiled with g++ do not share C++ runtime. This obviously is a problem if you need to propagate an exception from one DLL to another. MS Visual C++ does not have this issue.
yes it does, when you mix C runtimes (/MD vs /MDd for example), different C++ code is compiled with different incompatible options, or when you mix mingw and msvc (Those are all concrete problems I had to solve on windows at one point or the other BTW). Those problems are not c++ specific, but they are much more manageable in C than in C++. Interoperability with C++ from other languages is a known problem - given that numpy supports so many compilers and platforms, and that using 'weird' compilers is common in scientific computing, I don't think it worths the hassle in most cases. cheers, David
