Hi all,
I'm trying to open a new connection to a MySQL database by duplicating an
existing connection (as the docs[1] seem to indicate this is an acceptable
method) however it causes my application to segfault.
Here is a short example that reproduces the problem:
#include <mysql++.h>
int main(void)
{
mysqlpp::Connection main;
main.connect("db", "host", "user", "pass");
mysqlpp::Connection copy(main);
return 0;
}
(gdb) bt
#0 0x00007fa739228735 in free () from /lib/libc.so.6
#1 0x00007fa739cece27 in mysql_options (mysql=0x13feba8, option=<value
optimized out>, arg=0x13e85a8 "my") at client.c:3013
#2 0x00007fa73a03a863 in mysqlpp::ReadDefaultFileOption::set () from
/usr/lib/libmysqlpp.so.3
#3 0x00007fa73a035ca0 in mysqlpp::DBDriver::set_option () from
/usr/lib/libmysqlpp.so.3
#4 0x00007fa73a036773 in mysqlpp::DBDriver::connect () from
/usr/lib/libmysqlpp.so.3
#5 0x00007fa73a03690f in mysqlpp::DBDriver::DBDriver () from
/usr/lib/libmysqlpp.so.3
#6 0x00007fa73a0302c3 in mysqlpp::Connection::Connection () from
/usr/lib/libmysqlpp.so.3
#7 0x0000000000400ac4 in main () at test.cpp:7
What am I doing wrong??
Many thanks,
Adam.
