Folks, it is a *kernel* problem:
peter@ashburton[6:38pm]~-111> cc -v
Using built-in specs.
Configured with: FreeBSD/alpha system compiler
Thread model: posix
gcc version 3.1 [FreeBSD] 20020509 (prerelease)
peter@ashburton[6:38pm]~-112> c++ -static -o foo foo.c
peter@ashburton[6:39pm]~-113> ./foo
Abort(core dumped)

gcc-3.2.1 is not at fault. If it isn't kernel, it is library related.
But Matt Dillon did commit a couple of changes in this area very recently.
I think we should be looking around here:

Modified files:
sys/sys resource.h
sys/vm vm_mmap.c vm_unix.c
Log:
Part I of RLIMIT_VMEM implementation. Implement core functionality for
a new resource limit that covers a process's entire VM space, including
mmap()'d space.
(Part II will be additional code to check RLIMIT_VMEM during exec() but it
needs more fleshing out).
