We're using SGI as/ld. If you look at the SGI compiler output, there
are these funny notations in the .s file that get turned into DWARF2
debugging information by the assembler. But, we pass -g0 to the
assembler which keeps it from doing this kind of thing. Certainly,
the GCC 2.95.2 DWARF2 works OK, so *something* about what's different
is confusing things. I noticed that the order of some of the DWARF2
fields is different, but I'm not sure if/how that manners.
If you're still stuck tomorrow, let me know, and I can get you the
actual .o/a.out files to look at if that would be helpful.
