--- Comment #7 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to yjf.victor from comment #6) > According to my debugging on gdb, it failed to allocate the memory via the > `alloca()` function, and therefore resulted in Segmentation fault. If the problem is alloca, then you should be able to increase the stack size limit and have it work. Also i586-pc-interix3 is no longer supported IIRC.
