The memory leak detector was crashing. When using gc() you shouldn't use the CheckForMemoryLeaks() function from inside the same function, due to how it runs the atexit handlers.

* Sets size of unmapped pages at bottom of stack.
|
|
*
|
|
* This value will be rounded up to the host microprocessor page size,
|
|
* which is usually 4096 or 16384. It's important to write code in such
|
|
* a way that that code can't skip over the guard area. GCC has warnings
|
|
* like `-Wframe-larger-than=4096 -Walloca-larger-than=4096` which help
|
|
* guarantee your code is safe in this regard. It should be assumed the
|
|
* guard pages exist beneath the stack pointer, rather than the bottom
|
|
* of the stack, since guard pages are also used to grow down commit,
|
|
* which can be poked using CheckLargeStackAllocation().
|
|
*
|
|
* @param guardsize contains guard size in bytes
|
|
* @return 0 on success, or errno on error
