I now have an emacs built from changeset d97f522d3d3f with your patch.
After a few runs, I now have a gdb session with:

warning: realloc enlarge: VirtualAlloc error 87

Program received signal SIGSEGV, Segmentation fault.
0x000000040017209c in make_gap_larger (nbytes_added=0x1000) at 
../../src/insdel.c:411
411       *(Z_ADDR) = 0;

I will keep the gdb session running for further debugging.
