has anyone used the profiler (not tprof) recently?

i get a suicide when trying to run the simplest programs,
and was wondering whether it's a local problem or not.

e.g.

% cat tst.c
#include <u.h>
#include <libc.h>
void
main(int argc, char **argv)
{
}
% 8c -c tst.c
% 8l -p tst.8
% 8.out
8.out 863: suicide: sys: trap: fault read addr=0x7ffff014 pc=0x000017c1
% db 863
386 binary
page fault
