libodbc++ - Memory Leak - odbc

Question

`I am facing memory leak on each connection creation with database in libodbc++ library (0.2.5). I have copied valgrind log here. Used the below code to create and delete the connection. Any suggestion to fix the issue. Is libodbc++ stable to use ?
Sample Code:
`while(1)
{
Connection* con = DriverManager::getConnection(ConnectionString);
if(con != NULL)
{
delete con;
con = NULL;
}
}`
Valgrind Log:
==7534== 283,173,984 (1,074,640 direct, 282,099,344 indirect) bytes in 9,595 blocks are definitely lost in loss record 7,279 of 7,279 ==7534== at 0x4CE9B0F: malloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) ==7534== by 0x6FEB3B7: __gconv_open (gconv_open.c:74) ==7534== by 0x6FEB070: iconv_open (iconv_open.c:40) ==7534== by 0x3172BEB: unicode_setup (__info.c:601) ==7534== by 0x3136BD7: __SQLAllocHandle (SQLAllocHandle.c:492) ==7534== by 0x310DC4F: odbc::DriverManager::_createConnection() (drivermanager.cpp:140) ==7534== by 0x310DDBC: odbc::DriverManager::getConnection(std::__cxx11::basic_string<char, std::char_traits\<char="">, std::allocator\<char> > const&, std::__cxx11::basic_string<char, std::char_traits\<char="">, std::allocator\<char> > const&, std::__cxx11::basic_string<char, std::char_traits\<char="">, std::allocator\<char> > const&) (drivermanager.cpp:183) ==7534== by 0x</char></char,></char></char,></char></char,>
I have tried debugging libodbc++ library. SQLAllocHandle and SQLFreeHandle called properly for each connections and SQLFreeHandle returns SQL_SUCCESS. Memory not released by SQLFreeHandle. I didnt face connection leak. `
