I could reproduce it on a 486 client in the same configuration.

If you need my environment for reproducing the problem I could either give you access to my machine or send you the tree with the program to reproduce the problem. I don't know whether ld uses mmap. And it seems to occur always the first time after the binary image has been built (ld). Or where do you think mmap comes into the game? > > -- > Doug Rabson Mail: dfr@nlsystems.com > Nonlinear Systems Ltd. Phone: +44 181 951 1891 > > -- Chris Christoph P. U.
