FYI this is compiled from the gem, with GCC 4.1.1 (Red Hat 4.1.1-1). I included a trace below. Also, running in valgrind shows rather a lot of memory errors (but no leaks, so looking good there!) # ruby bug2.rb [... 1..90 elided ... ] 91 92 *** glibc detected *** ruby: double free or corruption (fasttop): 0x09ab4a38 *** ======= Backtrace: ========= /lib/libc.so.6[0x2bdf18] /lib/libc.so.6(__libc_free+0x78)[0x2c13ef] /usr/lib/libxml2.so.2(xmlFreeNodeList+0x16e)[0x7c0aeae] /usr/lib/libxml2.so.2(xmlFreeNodeList+0x96)[0x7c0add6] /usr/lib/libxml2.so.2(xmlFreeDoc+0xcb)[0x7c0abfb] ./../ext/xml/libxml_so.so(ruby_xml_document_free+0x2e)[0x9562fe] ruby[0x8070286] ruby(rb_newobj+0x46)[0x8070396] ruby(rb_data_object_alloc+0x10)[0x80703b0] ./../ext/xml/libxml_so.so(ruby_xml_node2_wrap+0x67)[0x9537b7] ./../ext/xml/libxml_so.so(ruby_xml_node_copy+0x6f)[0x95382f] ruby[0x805dd8d] ruby[0x805e981] ruby[0x805c404] ruby[0x805c396] ruby[0x8059b73] ruby(rb_yield+0x21)[0x805a3f1] ruby[0x8080b91] ruby[0x805dd8d] ruby[0x805e981] ruby[0x805c404] ruby[0x805d69b] ruby[0x805e57f] ruby[0x805e981] ruby[0x805c50b] ruby[0x805adaf] ruby[0x805e57f] ruby[0x805e981] ruby[0x805c50b] ruby[0x8059b73] ruby(rb_yield+0x21)[0x805a3f1] ruby[0x8080b91] ruby[0x805dd8d] ruby[0x805e981] ruby[0x805c404] ruby[0x805d69b] ruby[0x806940d] ruby(ruby_exec+0x16)[0x8069446] ruby(ruby_run+0x20)[0x8069470] ruby[0x805278f] /lib/libc.so.6(__libc_start_main+0xdc)[0x26f724] ruby[0x80526c1] ======= Memory map: ======== 0023c000-0023d000 r-xp 0023c000 00:00 0 [vdso] 0023d000-00256000 r-xp 00000000 fd:01 997991 /lib/ld-2.4.so 00256000-00257000 r-xp 00018000 fd:01 997991 /lib/ld-2.4.so 00257000-00258000 rwxp 00019000 fd:01 997991 /lib/ld-2.4.so 0025a000-00387000 r-xp 00000000 fd:01 997993 /lib/libc-2.4.so 00387000-00389000 r-xp 0012d000 fd:01 997993 /lib/libc-2.4.so 00389000-0038a000 rwxp 0012f000 fd:01 997993 /lib/libc-2.4.so 0038a000-0038d000 rwxp 0038a000 00:00 0 0038f000-003b2000 r-xp 00000000 fd:01 998148 /lib/libm-2.4.so 003b2000-003b3000 r-xp 00022000 fd:01 998148 /lib/libm-2.4.so 003b3000-003b4000 rwxp 00023000 fd:01 998148 /lib/libm-2.4.so 003b6000-003b8000 r-xp 00000000 fd:01 998149 /lib/libdl-2.4.so 003b8000-003b9000 r-xp 00001000 fd:01 998149 /lib/libdl-2.4.so 003b9000-003ba000 rwxp 00002000 fd:01 998149 /lib/libdl-2.4.so 003bc000-003ce000 r-xp 00000000 fd:01 104393 /usr/lib/libz.so.1.2.3 003ce000-003cf000 rwxp 00011000 fd:01 104393 /usr/lib/libz.so.1.2.3 00651000-0065c000 r-xp 00000000 fd:01 998151 /lib/libgcc_s-4.1.1-20060525.so.1 0065c000-0065d000 rwxp 0000a000 fd:01 998151 /lib/libgcc_s-4.1.1-20060525.so.1 00943000-0095f000 r-xp 00000000 fd:00 6427242 /home/usr/local/lib/ruby/gems/1.8/gems/libxml-ruby-0.5.0/ext/xml/libxml_so.so 0095f000-00960000 rwxp 0001c000 fd:00 6427242 /home/usr/local/lib/ruby/gems/1.8/gems/libxml-ruby-0.5.0/ext/xml/libxml_so.so 00d27000-00d39000 r-xp 00000000 fd:01 998161 /lib/libnsl-2.4.so 00d39000-00d3a000 r-xp 00011000 fd:01 998161 /lib/libnsl-2.4.so 00d3a000-00d3b000 rwxp 00012000 fd:01 998161 /lib/libnsl-2.4.so 00d3b000-00d3d000 rwxp 00d3b000 00:00 0 07bcb000-07cef000 r-xp 00000000 fd:01 104471 /usr/lib/libxml2.so.2.6.23 07cef000-07cf7000 rwxp 00124000 fd:01 104471 /usr/lib/libxml2.so.2.6.23 07cf7000-07cf8000 rwxp 07cf7000 00:00 0 07e2d000-07e32000 r-xp 00000000 fd:01 998156 /lib/libcrypt-2.4.so 07e32000-07e33000 r-xp 00004000 fd:01 998156 /lib/libcrypt-2.4.so 07e33000-07e34000 rwxp 00005000 fd:01 998156 /lib/libcrypt-2.4.so 07e34000-07e5b000 rwxp 07e34000 00:00 0 08048000-080ef000 r-xp 00000000 fd:00 5030041 /home/usr/local/bin/ruby 080ef000-080f1000 rw-p 000a6000 fd:00 5030041 /home/usr/local/bin/ruby 080f1000-08100000 rw-p 080f1000 00:00 0 09972000-09add000 rw-p 09972000 00:00 0 [heap] b7e00000-b7e21000 rw-p b7e00000 00:00 0 b7e21000-b7f00000 ---p b7e21000 00:00 0 b7f3c000-b7f6f000 rw-p b7f3c000 00:00 0 b7f8d000-b7f8f000 rw-p b7f8d000 00:00 0 bf7f5000-bf80b000 rw-p bf7f5000 00:00 0 [stack] Aborted -- Ross Bamford - [EMAIL PROTECTED] _______________________________________________ libxml-devel mailing list libxml-devel@rubyforge.org http://rubyforge.org/mailman/listinfo/libxml-devel
