Doesn't segfault here (32 bit Linux, r35789) (it does give a "double
free or corruption" after the error message, but we have another ticket
for that).

Could you please try again with a newer version of parrot, and also tell
us about your platform?

Oops, you're right. It gives
*** glibc detected *** ./perl6​: corrupted double-linked list​: 0x08713a08 ***

I just saw it crash and immediately assumed a segfault.

I now tried with r31857 and still get the error. (It doesn't happen if I type "say 8.bla;" to the interactive interpreter, btw)

I'm compiling with distcc over two computers. gcc --version on each gives​:
1. gcc (Debian 4.3.2-1) 4.3.2
2. gcc (Ubuntu 4.3.2-1ubuntu11) 4.3.2

I'm trying "make realclean && make perl6" (w/o distcc) now, and I'll see if it still shows up.

(I forgot perl Configure.pl)

No good. It still crashes the same way.

We did a fix today that should deal with double frees on exit, and I
expect it will have caught the one leading to this segfaulting. If you
still get the segfault rather than just an error, feel free to re-open.

Thanks,

Jonathan
