Another data point...  Earlier (I *think* it was this thread) someone
mentioned problems with trying to build glibc with gcc 3.x and "ls"
segfaulting.  I've recently upgraded portions of my system (including
libraries and compilers) with the packages from the Slackware 9.0 CD.
I expect a certain amount of pain (due to library version conflicts)
every time I go through the upgrade process, but this time the pain
feels different...  I absolutely cannot get getty and uugetty from the
getty-ps-2.1.0 package to work: segmentation faults.  Even tried building
from source: no good.  My old getty and uugetty binaries (version 2.0.7j)
seem to work ok with the new libraries, but rebuilding the 2.0.7j code
with gcc-3.2.2 results in segfaults.

The behavior seems to be independent of kernel version (2.5.70-2.5.72).
Here's the relevant version list (referenced libraries reported by ldd):

kernel 2.5.72
glibc 2.3.1
libtermcap 2.0.8
ld-2.3.1
gcc 3.2.2
binutils 2.13.90.0.18

The Slackware default install uses agetty rather than the getty-ps
package, which may partly explain why my particular symptom hasn't been
reported previously (to my knowledge).  I'm curious to know if this
problem exists with a virgin Slackware 9 installation, and will probably
have an answer by this weekend, time permitting.
