I passed your question on to one of my tech's and this is what I got
back:
Is this really a linker problem? No linker errors are reported and the
author says he can run the program. It only fails sometime after it's
started.
It could be that C++ needs to have its runtime environment initialized.
In the scenario where a C++ main program calls a Fortran routine which
calls a C++ function the C++ runtime environment is initialized by the
main program.
And in the scenario where a Fortran (or COBOL) main program calls a C++
function the c++ runtime is not initialized by the main program.
This help any?

Those are in libgcc.a. For example:
/usr/local/lib/gcc-lib/hppa1.0-hp-mpeix/3.3.1/libgcc.a
MODULE NAME : ../../gcc/libgcc2.c
VERSION : 87102412
LENGTH : 00002B7B
Sym C H X P Sym Sym Lset
Name Type Scope Name
---- - - - - ---- ----- ----
__udivdi3 0 3 3 entry univ
MODULE NAME : ../../gcc/libgcc2.c
VERSION : 87102412
LENGTH : 000029CF
Sym C H X P Sym Sym Lset
Name Type Scope Name
---- - - - - ---- ----- ----
__umoddi3 0 3 3 entry univ
What I've read about this (and I'm no expert) is that these two
functions can show up as unresolved when you attempt to link a non-gcc
application with gcc-linked libraries. I thought I'd pass that on in
case it helps!
