It almost sounds like an optimizer bug.  Have you tried building Swarm
with no optimization?

The toolchain consists of all the things that make it possible to
convert an Objective C program into an executable:  as, cpp, cc1, ld, 
the C library, Objective C support library, etc.

Is the gcc 2.8 you are using from Redhat or did you build it yourself?
Maybe there is some incompatibility there.  If there is a egcs or gcc 2.8.1
RPM, that might be worth a try too.  

Have you tried building Swarm with --disable-shared?  One
significant difference between 1.1 and 1.2 is that on GNU/Linux you'll
get shared libraries for Swarm things by default.  

Basically, I can't think of an explanation, although I suspect a code
generation or compiler configuration problem w.r.t. the C library dynamic
linker.
