MAC client crashes after launch

[supportreq]

Compiled the MAC client using QT 4 using homebrew on Marvericks.

The debugger gives the following error :

[supportreq]

The error was resolved after the code was compiled against mac os x 10.8.5 instead of 10.9.2...

The error appeared only when running the code on older os x version
