gcc "internal error" with 32-bit userspace, 64-bit kernel

gcc "internal error" with 32-bit userspace, 64-bit kernel

[Pierre Ossman]

I'm having a bit of a problem with the x86 32-bit compatibility and I
don't really know how to debug it.

The problem is that gcc fails some builds with "internal error" when
I'm running a 32-bit userspace on a 64-bit kernel. The same test
scenario with a 32-bit kernel works fine.

More specifically, I'm using Red Hat's mock tool on Fedora 9 to build
packages. It sets up a chroot:ed environment where (as far as I can
tell) everything is from the target system. Building for 32-bit Fedora
8 succeeds, but not Fedora 9 or RHEL 5.

Ideas on how to proceed? From what I've read, the 32-bit compatibility
of the kernel should be 100%.

Just tried to reproduce that with git of today. Did not happen.

Which kernel version are you using ?

Thanks,

Linux builder-f9.drzeus.cx 2.6.25.3-18.fc9.x86_64 #1 SMP Tue May 13 04:54:47 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux

Package I'm building is this one:

http://apt.drzeus.cx/oee/5/SRPMS/courier-0.59.0-1.el5.src.rpm

which also needs:

http://apt.drzeus.cx/oee/5/SRPMS/courier-authlib-0.60.4-1.el5.src.rpm

http://apt.drzeus.cx/oee/5/i386/courier-authlib-0.60.4-1.el5.i386.rpm
http://apt.drzeus.cx/oee/5/i386/courier-authlib-devel-0.60.4-1.el5.i386.rpm

Being built using this command:

mock -r epel-5-i386 --rebuild courier-0.59.0-1.el5.src.rpm

Result in build.log:
