>(alternatively, you can increase the stack size. maybe it's very small
the stack size is quite small by default - 512K. After some testing I
was able to figure out that it fails around 440 recursions... probably a
bit too small in comparison to the other *nixes.... but then I'll defer
to the experts in sre.
I was reading the August developer archives on the getrlimit and since
that seem to be available, it's probably the right way to implement the
stack check on Mac OS X.
Sure I can increase the default stack size - just a simple limit -h
before running it in the shell... I let it run until about 7K
recursions... even then it was only about 11MB and bumping the stack up
by 30K or so per recursion... and I still had nearly 100MB free... and
places to go. :-)
I'm going to write a bug report against Mac OS X and we'll see what
happens. In the meantime, you can hard code it to 440 and it will pass
the test... I've placed a patch on sourceforge that give the initial
support for detecting Mac OS X as part of the make file but I still have
to figure out how/where you defined MS_WIN64....
