The following program uses up all of my RAM in about 20 seconds: ------------------------------ #include <ginac/ginac.h> using namespace GiNaC;

If I compile it with this line instead, I have no similar problem:
while(1) basic x = symbol("x");
...any ideas? Am I confused about C++ (likely), or do I just have an old, buggy version of egcs, or is there a problem here?
I just tried it with an old egcs "gcc version egcs-2.91.60 Debian 2.1 (egcs-1.1.1 release)" and a new gcc "gcc version 2.95.2 20000220 (Debian GNU/Linux)". I can indeed see memory explode using egcs but not with gcc. This suggests the problem is with your compiler. Regards -richy. -- Richard B.
