It was suggested by our CTO that if these files were compiled as to

be able to debug with Open MPI without a problem. I'm not sure if this
is the best place to offer that suggestion, but I imagine it's not a bad
place to start. ;-)
Having just moved this to the "devel" list...
I don't think we'd mind doing what you propose if it's not too icky. These files are explicitly there for debuggers like TV, after all.
So how do we do that? (I don't know anything about STABS or DWARF)
Extracted from "man gcc" on Darwin host:
-gstabs
Produce debugging information in stabs format (if that is
supported), without GDB
extensions. This is the format used by DBX on most BSD
systems. On MIPS, Alpha and
System V Release 4 systems this option produces stabs
debugging output which is not
understood by DBX or SDB. On System V Release 4 systems this
option requires the GNU
assembler.
-gstabs+
Produce debugging information in stabs format (if that is
supported), using GNU
extensions understood only by the GNU debugger (GDB). The
use of these extensions is
likely to make other debuggers crash or refuse to read the
program.
