Hi there,

I'm trying to compile Objective-C code with gcc 2.7.2.1. Specifically, I want 
to use the gstep-base library on an i386 running FreeBSD 2.1.6. Half a year 
ago, when I first used the (then called) libobjects I experienced a floating 
point exception that forced a coredump on i386 architectures. That problem 
was due to a bug in config/i386/i386.md. The new gstep-base (I'm using 
0.2.12) requires the use of 960906-objc patches. I built the required gcc 
performing these steps:

1. unpack gcc-2.7.2
2. patch to version pl9 (I used the file gcc-2.7.2-2.7.2p-pl9.diff.gz which 
can be found on several FreeBSD mirrors - this patch fixes several bugs on 
intel 
3. stored configure file as configure.gcc-2.7.2p and put the configure.orig 
file in place
4. platforms in gcc-2.7.2 including the floating point bug)
5. use patch file gcc-2.7.2-2.7.2.1 to get a new gcc 2.7.2.1
6. use patch objc-960906-diff included in gstep-base
7. Manually merge the newly generated configure.file with the diffs in 
configure.gcc-2.7.2p

All patches worked as expected - no rejects, nu fuzz diffs, everything in 
place. To my surprise the new compiler was unable to create working 
Objective-C code using gstep-base library. Right now it dumps core due to a 
Bus error:

Program received signal SIGBUS, Bus error.
0x431b9 in __objc_init_install_dtable ()

This error is not specific to my code, it appears in any (simple) code.
Did someone realize the same problem? Am I doing something wrong?!
Maybe the gcc-2.7.2-2.7.2p-pl9 patch introduced new errors, in this case
(or in any case) I'd be glad to receive a patch for just fixing the
floating point exception and try again with it (the problem had to do with 
emit_call_insn as far as I recall).

Thanks in advance,

  Marcus.
