You mean this one:
subl $RESERVED_C_STACK_BYTES + 4*SIZEOF_LONG,%esp
subracting from %esp caused the program to exit? Surely not!

As far as I know, alloca just subtracts from %esp to allocate stack space,
unless you have to do something special on Win32 (unlikely - normal C
functions just allocate stack space at will).
still bemused...
