Comment (by Phyx-):

 That's great work @sergv!

 It does make some sense since `StgCRun.c` controls part of the stack
 allocations.
 Could you provide the preprocessed file `inplace/mingw/bin/gcc -E
 StgCRun.c -o StgCRun.i`

 along with the assembly output of the file compiled at `-O1` and `-O0`.
 `inplace/mingw/bin/gcc -O0 -S StgCRun.c -o StgCRun-O0.s` and similar for
 `-O1`.
