Hello. I have a reproducable problem which gdb says is ending up at
0x2818d862 in isatty() from /usr/lib/libc.so.3. A full back trace is
below. If this is a problem in FreeBSD, I'm very glad to do any
experiments that might be helpful. If it's a problem somewhere else,
any pointers on what I might do next would be great.
Thanks,
Tim
How to repeat:
I installed MySQL 3.23.2, then DBI-1.11. I compiled
Msql-Mysql-modules-1.2200, and ran the test suite. All but the first
test dumped core, all with this same error.
This is with -CURRENT as of Aug 10 @ 7AM (GMT). I did a complete
make buildworld; make installworld;, then I recompiled the kernel.
