Well, it was originally a RedHat 6.0 box, but I'm now running kernel
2.4.0-ac5, and I've upgraded most of the utilities to match; just about
everything is relatively new. The C library, on the other hand, is still
glibc-2.1.1-7; I don't know if that makes a difference. The egcs release
that doesn't have the problem is the one that came with that glibc. I
suppose it's about time to upgrade my glibc and try again...
(2.95 also miscompiles Qt (and that's _definitely_ an optimizer bug) on
this box, and I've had other things break too.)
P.S. after more testing, the exit bug is still the only one I've found.
Except the selection color defaulted to black for some reason but that's
no biggie. 1.1.6 works pretty good.
