Comment(by mikehh):
after running ./parrot t/pmc/eval_11.pbc to create the file
with the gcc build (with --optimize) (r43600) I get:
{{{
./parrot -t t/pmc/eval_12.pbc
0 set S1, "/tmp/VzIm7O67dC"
S1="(null)"
3 stat I0, S1, 1 I0=0

GC mark
GC collect
hello from foo_1
Segmentation fault
}}}
with the g++ build (with --optimize) (r43599) I get:
{{{
./parrot -t t/pmc/eval_12.pbc

29 set_args PC4

33 invokecc P0
P0=Sub=PMC(0xf8ce70 pc:0)
0 print "hello from foo_1\n"
hello from foo_1
2 set_returns PC1
4 returncc
35 set_returns PC4
37 returncc
FileHandle objects (like stdout and stderr)are about to be closed, so
clearing trace flags.
}}}
so it looks to me that the Segmentation fault is generated by GC mark/GC
collect
