Porting Rogue Wave Program From Solaris to Linux

[Steven Backus]

I inherited a Solaris c++ program that uses Rogue Wave and am trying to
port it to linux. It seg faults in this code:

for (int size = entries() - 1; size 1; --size)
{
RWOrderedIterat or vectofclusts_it er(*((RWOrdered *) at(size)));
CCluster* pc;
while ((pc = (CCluster*) vectofclusts_it er()) != NIL)
pc->writeChartTo(f out);
}
}

Unfortunately I don't know much about c++ or rogue wave. Can
anyone give me some hints about debugging this?

TIA,
Steve

That's by far too less code to say anything. Debugging tools are
platform-specific and thus off-topic here. I would try valgrind or efence
first and see if they help to pinpoint the problem. My bet is that the
code accesses some object which is already deleted or never existed.
