Can you supply a little bit more information? OS? Platform (32/64)? C-compiler? Did you call perl Configure.pl with any command-line options?

Thank you very much.

Sorry, this was on Ubuntu Linux 9.04, AMD64, using SunCC. Only command-line option was prefix.

Thanks.

Hello.

Can you retest it on r43414? I suspect it's same issue as in #1393.

Is there anyone on a 64-bit platform with SunCC who can re-test this?

Thank you very much.

I tried to reproduce this, but with Debian 5.0.4 ("Lenny"), SunCC 5.10 on amd64, and parrot r47640, rakudo ran out of memory trying to build src/gen/core.pir. (I have 0.5 GB available for parrot.)
