Subject: Segmentation fault on INSERT

Hi, I am forwarding Debian bug report #500788 - http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=500788 I'll copy here the original submitter's report - Thank you for your attention! ------------------------------------------ I just found out that a certain kind of INSERT statement can cause the DBD::PG module to produce a segmentation fault - reproduceably. Program received signal SIGSEGV, Segmentation fault. [Switching to Thread 0x7f09c22e56e0 (LWP 11781)] 0x00007f09c13fb850 in strcat () from /lib/libc.so.6 (gdb) bt #0 0x00007f09c13fb850 in strcat () from /lib/libc.so.6 #1 0x00007f09c0668ff2 in pg_st_execute () from /usr/lib/perl5/auto/DBD/Pg/Pg.so #2 0x00007f09c0655f50 in XS_DBD__Pg__db_do () from /usr/lib/perl5/auto/DBD/Pg/Pg.so #3 0x00007f09c0ca8708 in XS_DBI_dispatch () from /usr/lib/perl5/auto/DBI/DBI.so #4 0x00007f09c1e23e50 in Perl_pp_entersub () from /usr/lib/libperl.so.5.10 #5 0x00007f09c1e22332 in Perl_runops_standard () from /usr/lib/libperl.so.5.10 #6 0x00007f09c1e1d57f in perl_run () from /usr/lib/libperl.so.5.10 #7 0x0000000000400d0c in main () (gdb) q To see that yourself: - A table with (at least) two fields - A correct INSERT statement works: $db_session->do("INSERT INTO tbl(a, b) VALUES(?,?)", {}, "x", "y"); - With just a little type you get a segmentation violation: $db_session->do("INSERT INTO tbl(a, b) VALUES(??)", {}, "x", "y"); The perl part seems to notice that there are two "?", and two bind values, so everything's ok - but afterwards it crashes Regards, Phil
Thanks for the forward, fixed and will be a part of 2.11.2, making your way to a CPAN mirror now.
