Hello all,
I have a problem with Squeak running the 3.9-8 VM under Solaris (both x86 and SPARC). As soon as I access a socket, the VM crashes with a "Pollable Event" message. It seems as if there is a problem with the SIGIO handler. This used to work in earlier Solaris 10 revisions. Now I am running Solaris 10 11/06 at the latest patch level on SPARC and Solaris Express Comunity Release Build 60 on x86. Any hints how to fix this will be appreciated.
After a debug session I have finally found a solution for the problem: In aio.c the function aioInit() sets a signal handler for SIGIO. Alas this doesn't work as expected for Solaris. I have replaced signal(SIGIO, forceInterruptCheck); with sigset(SIGIO, forceInterruptCheck);
Now Squeak works again and has no problems with sockets anymore.
Regards Andreas
