[Vm-dev] VM is being buil without debug info?

[Igor Stasenko]

I use similar setup, and mine shows it just fine:

NBCogCocoaIOSConfig new
	generateForDebug;
	"generateForRelease;"
	addExternalPlugins: #( FT2Plugin  );
	addInternalPlugins: #( UnixOSProcessPlugin );
	 generateSources; generate.
.

(gdb) bt

Make sure you use right executable (clean up everything and rebuild
from scratch)..
