Hurd test



Hello,

today I retried a very simple test which I had done in the past with
different
versions of gnumach, hurd, tarballs from Markus, ..., but the same results.

In this test, I used the latest gnumach/hurd from the debian ftp server.

The test is started by a simple shell command line. It runs some time -
depending on your memory and swap size, until the hurd crashs. To reduce
the time needed to crash, please reduce main memory and/or swap size.

I tried to analyse the problem, but I need some advice to get it solved.
Obviously, some program (most probably ext2fs.static) eats all memory.
Do you - the other hurd users - get the same results? How can I get on
with the analysis of this problem?

Regards,
Stefan

Here is the test and its output. Because the total output is very long,
I replaced large parts (without new information) by ...
The first line was used to start the test. Please try it.
