Summary: #8870 added as a temporary work around a much higher initial reserve and committed stack space of 2mb. This is causing problems with other windows applications. The hack was supposed to be temporary untill we could emit `__chkstk` instructions. But GCC can emit stack checks automatically for us if `-fstack-check` is passed. This will then emit calls to `___chkstk_ms` before stack allocations. ``` 633de0: 48 83 e0 f0 and $0xfffffffffffffff0,%rax 633de4: e8 07 0c 0d 00 callq 7049f0 <___chkstk_ms> 633de9: 48 29 c4 sub %rax,%rsp ``` The hack is now no longer needed.
