Yes, this is a resource limit. The default stacksize limit is
512k. Use 'unlimit' in the shell before running the program,
or add some setrlimit() code to the program. The maximum size
is 8Mb, on i386 at least (see /usr/include/machine/vmparam.h).

You _could_ probably put any of the defines in the config file
(options DFLSSIZ=somebignumber, etc), because vmparam.h has
#ifndefs around those defines. But if some user program includes
<machine/vmparam.h> it might get very confused by that, so I don't
think that would be a good idea.
