Hard to tell, the HP linker is very picky about symbols being in the
right subspace, so the output from the code you're profiling is
tickling a problem in the mangler, I'd say. If you have an assembler
dump (i.e., the output of -ddump-raw-asm and the file produced by
-keep-s-file-to) at hand, I'd be happy to have a look.
