Bug #43537 for Cache-Memcached-Fast: _multi called with empty array causes segfault

Mon Feb 23 09:19:42 2009 wsnyder [...] wsnyder.org - Ticket created

Calling cas_multi on an empty array should just do nothing. Instead on Suse10.3/perl5.8.8 it causes a segmentation fault. The same bug occurs in other _multi functions too. my @to_update = (); $memd->cas_multi(\@to_update); segmentation fault Backtrace (sorry didn't compile with debug): 70x00002b538c657a4c in XS_Cache__Memcached__Fast_set_multi (my_perl=<value optimized out>, cv=<value optimized out>) at Fast.xs:766 66 cas = SvUV(*av_fetch(av, arg, 0)); #0 0x00002b538c657a4c in XS_Cache__Memcached__Fast_set_multi (my_perl=<value optimized out>, cv=<value optimized out>) at Fast.xs:766 #1 0x0000000000486bb3 in Perl_pp_entersub () #2 0x0000000000468f8e in Perl_runops_debug ()

I should point out that the above calls using a reference instead of with an array, which is a usage error, but obviously it still shouldn't segfault.
