Based on the position of the warn statements it's happening at the "$buf
~= $socket.recv(1);" line.

Comment(by jkeenan):

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.[[BR]]

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.)
