           Summary: internal compiler error: in loc_descriptor_from_tree, at
                    dwarf2out.c:8780
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

 GCC build triplet: ia64-linux
  GCC host triplet: ia64-linux
GCC target triplet: i386-gnu

When compiling glibc for i386-gnu, I get the following error:

Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

With the proprocessed source, the bug triggers as:

$ i386-gnu-gcc -O1 -g -c foo.c

-O2 triggers too.

I'll try to test a native compile, or one targetted to i386-linux.  I suspect
this will show up on at least one of those.
