[Quickfix-developers] crashes with latest versions, sample code attached ...

[H. S. <st...@pa...>]

guys,

i came accross some weired segfaults using the quickfix library. below
you can see a simple code snippet which crashes versions 1.12.2, 1.12.3
as well as current svn. the versions up to 1.12.1 work ok.

could one of you guys explain whats either wrong with that code snipped
or what changes have been made to quickfix to crash it?




#include <quickfix/fix42/Message.h>

int main (int ac, char** av)
{
    try{
        FIX42::Message m( FIX::MsgType("F") );
    }
    catch( ... ) {}
    return 0;
}
