I'm not really sure about this. But, it looks it uses dlopen as
several files contain the string ``dlopen''.

Guess what! Things are getting worse. (At least it seems to me that
way.) I started up gdb and and did ``help set'' to find out some
stuff. Gdb gave me the first page of the help screen as usual, but as
I hit return key to go onto the next page, it died on signal 3 with
following message after showing the second page:
gdb internal error: Memory corruption
Quit (core dumped)
This error is not affected by ld.so.hints change. It happens
regardless of whether kaffe runs or not. So, I guess now we have to
do some investigation on gdb.... ;_)
Do you think having CFLAGS=-O -pipe -m486 in /etc/make.conf coud be
causing these errors? After I discovered gdb's error, I rebuilt
/usr/src/gnu/usr.bin/{gdb,ld} with -O and -m486 removed from
/etc/make.conf, but things don't change. Should I do make world
without those flags and try again?
