I'm able to duplicate this on Postgres 8.4 (Debian Etch, XML::LibXML from CPAN). Here's the backtrace from the crash: #0 0x082f3cf1 in MemoryContextAlloc () #1 0x082c3f8a in xml_palloc () #2 0xb7dfa548 in xmlInitCharEncodingHandlers () from /usr/lib/ libxml2.so.2 #3 0xb7e0195e in xmlInitParser () from /usr/lib/libxml2.so.2 #4 0xb7dff2ef in xmlCheckVersion () from /usr/lib/libxml2.so.2 #5 0xb573af2e in boot_XML__LibXML () from /usr/local/lib/perl/5.8.8/auto/XML/LibXML/LibXML.so #6 0xb587981b in Perl_pp_entersub () from /usr/lib/libperl.so.5.8 #7 0xb5877f19 in Perl_runops_standard () from /usr/lib/libperl.so.5.8 #8 0xb5819b6e in Perl_magicname () from /usr/lib/libperl.so.5.8 #9 0xb581a844 in Perl_call_sv () from /usr/lib/libperl.so.5.8 ... Is it supposed to be OK to call xmlCheckVersion() more than once? -- DLL -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
