Hi!
i still can reproduce the bug, with perl 5.8.8-7, on i386 and sparc64,
but not on amd64.
also, your behavior "program sits there doing nothing but no crash"
suggests that there is indeed a bug: the program should not sit doing
nothing - there is no loop there.
here are the crashes:
1) on sparc64:
$ perl /tmp/test.pl
*** glibc detected *** perl: double free or corruption (!prev): 0x00125ac8 ***
Aborted
2) on i386:
$ perl /tmp/test.pl
*** glibc detected *** perl: double free or corruption (!prev): 0x0825ab58 ***
