Thanks for the bug report. I'm not entirely sure how these crashes are happening. The first appears to happen when "DocType" is not set in the omf file. In this case, there are checks in librarian which should stop this happening. Can you please try with rarian 0.8.x and see if the issue persists. If it does, can you possibly send one of the faulting files (if you can determine this). Thanks. In the second case, there appears to be documents in the info "dir" file before categories, confusing the parser. I've checked a check for this in current SVN which should appear in 0.8.1. 2008-07-29 Don Scorgie <Don@Scorgie.org> * librarian/rarian-info.c: Check for documents appearing between *Menu and the first category. bug #12515 I'll mark this bug as accepted for now. |

Hi, while trying to replace scrollkeeper we got some sefgaults with rarian ( 0.6.0 ) on Frugalware Linux. We notice first segfault while building some package , quite easy to reproduce for me. Here a bt : (gdb) run hu_HU scrollkeeper_cl.xml Starting program: /usr/bin/rarian-sk-get-cl hu_HU scrollkeeper_cl.xml Program received signal SIGSEGV, Segmentation fault. 0xb7d6e143 in strlen () from /lib/libc.so.6 (gdb) bt #0 0xb7d6e143 in strlen () from /lib/libc.so.6 #1 0x0804e4f3 in TiXmlString::operator= (this=0x8063d08, copy=0x0) at tinystr.h:112 #2 0x0804e527 in TiXmlNode::SetValue (this=0x8063ce8, _value=0x0) at tinyxml.h:471 #3 0x0804e560 in TiXmlText (this=0x8063ce8, initValue=0x0) at tinyxml.h:1060 #4 0x0804de7d in get_docs (reg=0x805b148, pParent=0x8077e50) at rarian-sk-get-cl.cpp:109 #5 0xb7f219df in rrn_for_each_in_category (funct=0x804db8c <get_docs(_RrnReg*, TiXmlNode*)>, category=0x8063430 "General|Licenses", user_data=0x8077e50) at rarian-main.c:137 #6 0x0804e194 in process_node (pParent=0x8077e50) at rarian-sk-get-cl.cpp:140 #7 0x0804e1bc in process_node (pParent=0x8077cd8) at rarian-sk-get-cl.cpp:150 #8 0x0804e1bc in process_node (pParent=0x805c4f0) at rarian-sk-get-cl.cpp:150 #9 0x0804e354 in main (argc=3, argv=0xbfd9a014) at rarian-sk-get-cl.cpp:223 (gdb) l *0x0804e4f3 0x804e4f3 is in TiXmlString::operator=(char const*) (tinystr.h:112). 107 } 108 109 // = operator 110 TiXmlString& operator = (const char * copy) 111 { 112 return assign( copy, (size_type)strlen(copy)); 113 } 114 115 // = operator 116 TiXmlString& operator = (const TiXmlString & copy) (gdb) l *0x0804e527 0x804e527 is in TiXmlNode::SetValue(char const*) (tinyxml.h:471). 466 Comment: the comment text 467 Unknown: the tag contents 468 Text: the text string 469 @endverbatim 470 */ 471 void SetValue(const char * _value) { value = _value;} 472 473 #ifdef TIXML_USE_STL 474 /// STL std::string form. 475 void SetValue( const std::string& _value ) { value = _value; } (gdb) l *0x0804e560 0x804e560 is in TiXmlText (tinyxml.h:1061). 1056 element, set the parameter _cdata to 'true' 1057 */ 1058 TiXmlText (const char * initValue ) : TiXmlNode (TiXmlNode::TEXT) 1059 { 1060 SetValue( initValue ); 1061 cdata = false; 1062 } 1063 virtual ~TiXmlText() {} 1064 1065 #ifdef TIXML_USE_STL (gdb) Is trying to strlen(NULL) ...
