GCC for Windows 64 & 32 bits

Mingw-w64

Mingw-w64 is an advancement of the original mingw.org project, created to support the GCC compiler on Windows systems. It has forked it in 2007 in order to provide support for 64 bits and new APIs. It has since then gained widespread use and distribution.

The development and community are very active and welcoming with new contributors every month and simple installers.

For the reference, libxml2 build withMinGW-w64-provided gcc 8 fails with the same error when -fno-omit-frame-pointer is used (but not without it).

I gave this another spin and tested following toolchains in a clean VM with the official installer: i686-8.1.0-posix-sjlj-rt_v6-rev0 -> works x86_64-8.1.0-posix-sjlj-rt_v6-rev0 -> broken x86_64-8.1.0-posix-seh-rt_v6-rev0 -> works So the issue is really only with sjlj with 64bit. I still don't know if the bug is in gcc or gdb though. Any idea how to find that out? Kai, it would be great if you could have a look, it is very easy to reproduce based on Max's instructions.
