Hello,

I have been building a mixed C++/Fortran package in 64-bit mode using GCC 4.0.1 (build 5367) packaged with the latest version of XCode and Absoft ProFortran (F95 compiler) 9.2. It complains (and never has before in various 32-bit incarnations) about the following:

"ld64-62.1 failed: duplicate symbol IBuffer::~IBuffer()in /Home/fparnold/progs/qchem/ccman/ccman.a(ibuffers.o) and /Home/fparnold/progs/qchem/ccman/ccman.a(ibuffers.o)"

Any suggestions on how to fix this? The offending routines are attached. As noted before, this builds correctly using XLF/XLC (32-bit), Intel/AMD (64 or 32-bit), or large machines. The routines in question haven't changed since 2001.

Thanks.
