Yeah, for me it also recurses till the exception is hit, and then
processes that successfully. This is effectively identical to a case
in the standard regression tests, which also intentionally recurses
till stack overflow. Since we have FreeBSD machines in the buildfarm,
it is reasonably safe to conclude that this isn't a generic FreeBSD
bug. I suspect the OP has used some unusual configure/build option
or linked in some nonstandard code that is causing the available
stack space to change unexpectedly.
