[mp2] segfault when connect to database
httpd2 2.0.47, mod_perl 1.99_09
------------------------------
httpd does segfault when I try to connect to the database (mysql or
interbase). It faults somewhere in libnss_db.so. It works well if I
remove libnss_db* from the system.
Here is the part of programm stack from core:
#0 0x00000000 in ?? ()
#1 0x4075de1e in db_open () from /lib/libnss_db.so.2
#2 0x4075ded0 in internal_setent () from /lib/libnss_db.so.2
#3 0x4075d62e in _nss_db_endservent () from /lib/libnss_db.so.2
#4 0x4075d8c3 in _nss_db_getservbyname_r () from /lib/libnss_db.so.2
#5 0x40358733 in __getservbyname_r (name=0x405a42f7 "mysql",
proto=0x405a42f3 "tcp", resbuf=0x4038bb7c, buffer=0x86a8a70 "", buflen=1024,
result=0xbffff148) at ../nss/getXXbyYY_r.c:200
#6 0x403585e1 in getservbyname (name=0x405a42f7 "mysql", proto=0x405a42f3 "tcp")
at ../nss/getXXbyYY.c:145
#7 0x405949fb in mysql_once_init ()
from /usr/lib/perl5/site_perl/i386-linux/auto/DBD/mysql/mysql.so
#8 0x4059711b in mysql_init ()
from /usr/lib/perl5/site_perl/i386-linux/auto/DBD/mysql/mysql.so
#9 0x4058bf4a in mysql_dr_connect ()

Can you try reproducing the problem with an external program and then mod_cgi?
I don't see where mod_perl is involved here.
Thanks!

So it can't be fixed until we can see the backtrace and be able to reproduce it.

I noticed a while back that when I use PostgreSQL/W2K/2.0.46/mp1.99_10 I get
a segfault _when Apache shuts down_. I don't have it compiled such that I
can do a backtrace.
