The mingw version always produces NaN results when Out-Of-Core is enabled

[jfry207]

I compiled MUMPS with MinGW on windows (GCC 12.2.0)，It solves large scale problems correctly, but when I turn on OOC ICNTL(22)=1, the result is always Nan

BTW: The MSVC+OneAPI version works fine when i turn on OOC solving the same problem

I don't know if the MUMPS developers have tried this configuration. Is this using MPI (default is using MPI). Or did you turn MPI off like:

cmake -Dparallel=off
