State-Changed-Why:
    Please accepts our apologies that nobody has looked into this
    report until now. Do you still have the sources and can
    reproduce the error? We would need the preprocessed source
    file, as described in the bug reporting instructions which
    you can find from the gcc homepage http://gcc.gnu.org.
    
    By the way, are you absolutely sure that you are using
    gcc3.2 for your compilation (check with gcc -v)? The
    output upon the internal error does not mention the 
    gcc web page, which it should with 3.2...

 I just tried re-building the source from my tarball, and I cannot reproduce
 the error. I assume this inability is from creeping changes in our UNIX
 environment over the past three months...
 
 Thanks for checking in, I'll make a more thorough/complete report should
 I come across problems again.

 The way this goes is: you see which file the compiler barfs at. Go into 
 this directory and do the exact same command line that was used to compile 
 it previously (when you used make). This command line is the last one that 
 is printed, of course. Then just add -save-temps to the command line. The 
 compiler will still die, but it will have generated a .i file. This is the 
 file we need.
 
 Thanks

 There's no way I can pick out from the mozilla source code which file(s)
 are necessary to reproduce the bug. As much as I hate the presentation,
 all I have is a tarball of my build tree.

 I apologize sincerely at my lack of a concise method of reproducing the
 error.

 Yes, though I'm not using gcc 3.2.1, and I have not tried building the
 most recent mozilla source code.

 I may have omitted that portion of the error message in my report.

A mozilla 1.1 build produced the following error, and asked nicely if I would report it please.

gcc -o s_scalbn.o -c -DOSTYPE=\"SunOS5\" -DOSARCH=\"SunOS\" -DOJI   -I../../../dist/include/js -I../../../dist/include -I/scratch/mariachi/lanclos/mozilla/dist/include/nspr         -fPIC  -Wno-long-long -O3 -mcpu=ultrasparc -pthreads -pipe  -DNDEBUG -DTRIMMED -D_IEEE_LIBM   -include ../../../config-defs.h -DMOZILLA_CLIENT -Wp,-MD,.deps/s_scalbn.pp s_scalbn.c

Please submit a full bug report,
with preprocessed source if appropriate.
>How-To-Repeat:
Download mozilla 1.1 source to your favorite Solaris 2.6 machine, after compiling libIDL, GTK, and glib as static modules, and configure it with CFLAGS="-O3 -march=ultrasparc".

make.

I'll create a tarball of the offending mozilla source tree, just in case anyone wants it.
>Fix:
I was going to try turning down the optimization and see if that avoided the error. That doesn't fix anything, of course...
