You are my hero. This one is totally lost on me... never seen anything
like it. So, reduced down to bare bones, to make things not crash on
pfInit using Redhat 9 and a super-simple test case, do this:
int main (int argc, char * argv[]) {
static int ignore = 0;
if (ignore) { FILE * fp = fopen("", "r"); }
pfInit();
...
}
But why does this work, since it doesn't even do anything? Perhaps it
has something to do with some static initialization or linking issue
between Performer & libc. Performer developers at SGI... might want to
look into this.
Repeated low-bowing while backing toward an exit...
