[ID 19991110.004] passing '-I' flag to embedded interpretercauses core dump
Message ID:

While embedding a Perl interpreter into an existing application framework, I
was causing some puzzling core dumps and/or heap crushes. A C++ program to
replicate the problem follows. The workaround was not to pass "-I" to
perl_parse() but to relegate @INC manipulations to the Perl programs
themselves.

P.S. I've tried to submit this previously, but couldn't find it in the
database so I'm resubmitting. If this is a duplicate, I apologize in
advance.
