Hi,
same problem here. I can trigger segfaults with ruby using ODBC
independent (?) of the ODBC driver used (tested with MySQL and MS SQL).
This most common ruby script
==========================================================
require 'dbi'
dbh = DBI.connect('DBI:ODBC:abcd', 'efgh', 'ijkl')
sth = dbh.prepare('SELECT 1')
sth.execute
print "pre\n"
p sth.fetch_array
print "post\n"
==========================================================
results in
==========================================================
$ ./test.rb
pre
/usr/lib/ruby/1.8/dbd/odbc/statement.rb:41: [BUG] Segmentation fault
ruby 1.8.7 (2008-08-11 patchlevel 72) [i486-linux]
Aborted
==========================================================
It seems to be an issue with the row description returned by the ODBC
manager, but I didn't dig into the iODBC/libodbc-ruby1.8 code to know
for sure.
libodbc-ruby1.8 (used by libdbd-odbc-ruby1.8) is build against the iODBC
manager in Debian Lenny. I build libodbc-ruby1.8 against unixODBC - and
now it works:
==========================================================
$ ./test.rb
pre
[1]
post
==========================================================
Regards,
Thomas
PS: The bug should be filed against libodbc-ruby1.8 with severity grave
IMHO.
