stack-limit: bug: not handling RLIM_INFINITY.
* gc.c (gc_init): We must check rlim_cur for the RLIM_INFINITY
value indicating unlimited stack, and not misuse this value as a
limit number, otherwise hilarity ensues. This reproduced on
an older platform with make 3.81, which calls setrlimit to
bring about an unlimited stack, passed on to child processes.
Because of this txr segfaulted, as a consequence of a false
positive.
* tests/012/stack.tl (stack-limited): New variable which
indicates whether there is a stack limit. If there isn't, we
avoid running the fork-based test case. Also, we set the stack
limit to 32768 so we have a limit against which to run some of
the tests.
