@laurentbercot Not if the size passed to alloca is so large as to move the stack pointer into writable memory. -
@RichFelker I was thinking OOM, not segfault. You can't pull that off on 64-bit systems (assuming overcommit is limited). 32-bit, though... -
@RichFelker I'm imagining a system where stack alloc crashes when it should trap but doesn't. Is it possible? Efficient? Already a thing?
