First, I'd like to apologize that I wasn't able to extract the problematic
code. I hope somebody more experienced will find the way how to do it.
Problematic code is in enblend, which can be downloaded from cvs using cvs:
cvs -z3 -d :pserver:anonym...@enblend.cvs.sourceforge.net:/cvsroot/enblend
While building the current 4.3.3 branch with ada support enabled, this happens:
i686-pc-linux-gnu-gcc -c -g -fkeep-inline-functions -gnatpg -gnata
-nostdinc -I- -I. -Iada -I../../gcc/ada ../../gcc/ada/ali.adb -o ada/ali.o

Happens when bootstrapping with 4.4 only; after applying the patch I've
attached, it aborts with other errors.

I think it can be somewhat connected to bug #32896.
Unlikely.
Anyways does it segfault when compiled at -O0. How about -O2
-fno-strict-aliasing ?

I've already tested it with -O2 -fno-strict-aliasing without success. I'll test
it with -O0.

Works with 4.3:
Well, not really. gfortran 4.1/4.2/4.3 only call the module procedure, but for
call f() the contained procedure should be called, which does not work with
4.[1-3].

This should probably be closed as WONTFIX. The report is
against FreeBSD 5.3, which is ancient. The FreeBSD Ports
Collection currently has port/lang/gcc34, which

Thanks! Your patch should be applied when the trunk is reopened.
One minor nit, the ifdef guard in the hunk for linux-atomic.asm can be
removed because linux-atomic.asm is specific to linux and ELF.
