Solaris 8/Oracle 8 C++ program segmentation fault on connect

I'm running a C++ program on a Solaris 8 system, with Oracle 8.1.7 installed. I'm trying to connect to an Oracle 7.3.4 database. In the parent process, the exec sql connect work fine. However, in forked processes, the exec sql connect fails with a segmentation fault, as you can see in the backtrace below:

This codes functions fine if it is compiled against Oracle 7.3.4 (and has been fine for about 3 years)

I can write sample programs using the same database connection libraries that use for the above program, and they work fine. I can also fork() additional processes, and connect to the database fine.

Why would a child process die with a segfault when trying to connect? I've verified the parameters, and they all look fine. I'm using this make sequence to compile all my code:

./qproc user=userid/password_at_sid \
 lines=y sqlcheck=full code=cpp cpp_suffix=cc test.pc g++ -fno-implicit-templates -ggdb -gstabs+ -DCOMPILE -DSQLCA_NONE -I/home/oracle/OraHome1/precomp/public -I../support -c -o test.o test.cc
g++ -otest test.o -L../support -ltemplates -lsupport -L/home/oracle/OraHome1/lib -lclntsh -L. -ldatabase -L../support -lsupport
rm test.cc

The system I'm developing on is not hosting any databases; it's acting as a client only.

Could this be a proc configuration/option problem? After reading the documentation, I'm not sure it is, but I'm open to any hints...

Any suggestions would be much appreciated. I've searched usenet, but not found any hits on this particular problem. Searching on Oracle's site has not yielded any results either.

Thanks!
