I debugged a crash of vmr which occurred while building fsharp repo on s390x. Looking at the crash, the stack had overflowed.

I had not seen such an overflow on x64/arm64 (using CoreCLR). Looking closer at the implementation, with CoreCLR, the stack size follows the Linux configured limit (ulimit -s, typically 8MB), while for Mono it is hard-coded to 2MB (on 64-bit, and 1MB on 32-bit):

When I changed the hard-coded size to 8MB on Mono, the stack overflow crash no longer occurred.

This issue is for changing the stack size on Mono so it matches with what CoreCLR does (in a similar environment).
