[odb-users] Compiling ODB with /MTd

Thu Mar 13 11:59:47 EDT 2014

<div dir='rtl'> Hi Boris, The&nbsp;libodb-sqlite-vc11 project you provide is compiling /MDd in debug (linking to DLL), however our program is compiling /MTd (statically linked). Although the&nbsp;libodb-sqlite-vc11 does compile &nbsp;/MTd, when executing an erase query on our program we get debug heap corruption assert, this seems to be related to the std::string destructor. We tried several compilations options and the problem seems to be exclusively related to libodb-sqlite-vc11, meaning regardless of the compiling options to ODB and SQLite, when the libodb-sqlite-vc11 setting change to /MTd the problem happens. When both the app and the libodb-sqlite-vc11 are compiled /MDd, everything works fine, the erase query is executed and the recordes are erased. Can you please take a look ? Thank you,Erez. Sample code : unsigned long long access::object_traits_impl&lt; ::CIndividualFactMainData, id_sqlite &gt;::erase_query (database&amp;, const query_base_type&amp; q)&nbsp; {&nbsp; &nbsp; using namespace sqlite; &nbsp; &nbsp; sqlite::connection&amp; conn (&nbsp; &nbsp; &nbsp; sqlite::transaction::current ().connection ()); &nbsp; &nbsp; std::string text (erase_query_statement);&nbsp; &nbsp; if (!q.empty ())&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; text += ' ';&nbsp; &nbsp; &nbsp; text += q.clause (); &lt;-------------------problem happens here&nbsp; &nbsp; } &nbsp; &nbsp; q.init_parameters ();&nbsp; &nbsp; delete_statement st (&nbsp; &nbsp; &nbsp; conn,&nbsp; &nbsp; &nbsp; text,&nbsp; &nbsp; &nbsp; q.parameters_binding ()); &nbsp; &nbsp; return st.execute ();&nbsp; } Stack Calls : &gt;	SQLite_Test_1.exe!_free_dbg_nolock(void * pUserData, int nBlockUse) Line 1424	C++&nbsp;	SQLite_Test_1.exe!_free_dbg(void * pUserData, int nBlockUse) Line 1265	C++&nbsp;	SQLite_Test_1.exe!operator delete(void * pUserData) Line 54	C++&nbsp;	SQLite_Test_1.exe!std::allocator&lt;std::_Container_proxy&gt;::deallocate(std::_Container_proxy * _Ptr, unsigned int __formal) Line 586	C++&nbsp;	SQLite_Test_1.exe!std::_String_alloc&lt;0,std::_String_base_types&lt;char,std::allocator&lt;char&gt; &gt; &gt;::_Free_proxy() Line 683	C++&nbsp;	SQLite_Test_1.exe!std::_String_alloc&lt;0,std::_String_base_types&lt;char,std::allocator&lt;char&gt; &gt; &gt;::~_String_alloc&lt;0,std::_String_base_types&lt;char,std::allocator&lt;char&gt; &gt; &gt;() Line 656	C++&nbsp;	SQLite_Test_1.exe!std::basic_string&lt;char,std::char_traits&lt;char&gt;,std::allocator&lt;char&gt; &gt;::~basic_string&lt;char,std::char_traits&lt;char&gt;,std::allocator&lt;char&gt; &gt;() Line 965	C++&nbsp;	SQLite_Test_1.exe!odb::access::object_traits_impl&lt;CIndividualFactMainData,1&gt;::erase_query(odb::database &amp; __formal, const odb::sqlite::query_base &amp; q) Line 1348	C++&nbsp;	SQLite_Test_1.exe!odb::database::erase_query&lt;CIndividualFactMainData&gt;(const odb::query&lt;CIndividualFactMainData,odb::sqlite::query_base&gt; &amp; q) Line 470	C++&nbsp;	SQLite_Test_1.exe!CIndividualFactsMgr::RemoveFacts(long individualId, const char * factToken, const char * type) Line 179	C++&nbsp;	SQLite_Test_1.exe!main(int argc, char * * argv) Line 189	C++&nbsp;	SQLite_Test_1.exe!__tmainCRTStartup() Line 240	C&nbsp;	SQLite_Test_1.exe!mainCRTStartup() Line 164	C&nbsp;	kernel32.dll!7614495d()	Unknown&nbsp;	[Frames below may be incorrect and/or missing, no symbols loaded for kernel32.dll]	&nbsp;	ntdll.dll!770298ee()	Unknown&nbsp;	ntdll.dll!770298c4()	Unknown<div> </div></div><hr><div style="background-color:white;color:black;">Walla!
