I am having a software problem(GIMPS), and am hoping somebody has had a
similar expierience. I have a 486 DX4-100 running linux (Slackware,
kernel 2.0.34, 16 meg of RAM) and I cant get either of the linux versions
available to work on my machine.

I have essentially the same problem, mprime segfaults on a 486, I tried
with both Slackware 3.5.0 and RedHat 5.2, exact same library and kernel
versions as the ones in the pentium machines I run mprime on.
I too had problems (on a pentium) with mprime, starting about version 14.
I finally tracked it down to some lines in my /etc/profile like this:
ulimit -Hs 32768
ulimit -Hd 65536
ulimit -Ss 16384
ulimit -Sd 32768
(Old linuxes could get bogged down by buggy programs infinitely
growing the stack or like that; the above lines set address space
limits to prevent problems.) (Newer linuxes don't need this.)
The way mprime is linked, it appears to have an enormous data segment.
It isn't actually enormous, just at a high address. Make sure you
don't have any limits set for it:
$ ulimit -a
core file size (blocks) unlimited
data seg size (kbytes) unlimited
file size (blocks) unlimited
max memory size (kbytes) unlimited
stack size (kbytes) unlimited
cpu time (seconds) unlimited
This fixed the problem I was having. I'm also running it on a 486/66
without segfaults.
