I have installed Redhat 5.2, Oracle 8.0.5, and perl DBD::Oracle and DBI. I am getting a segmentation fault when I execute a sql query with over 20 fields. I tried this query in sqlplus on linux, and receieved the same segmentation fault at that limit. I have tried the same query using both perl and sqlplus on NT and it works. After this I have tried to install qpopper-2.52-1.i386.rpm, and when I try to run /usr/sbin/popauth, I get a segmentation fault. I have been able to develop a cgi that executes my query by splitting it into three seperate query strings. Both previously mentioned segmentation faults result in a core dump.
I am not sure what the DBD::Oracle module does to the perl binary in 5.2 - however, more recent combinations of perl/DBD::Oracle are working fine on our servers.
