And the last obligatory question: It really is crashing only on opening new main package, right?
However, I'm suspecting this is a compiler error now. (maybe O3 optimization level related?). I'll try other options (O2 and GCC), report back asap.

	for(int i = 0; i < packages.GetCount(); i++) {
		const PkInfo& pkg = packages[i];
		DDUMP(IdeImg::GetCount());

//		alist.SetDisplay(alist.GetCount() - 1, 0, pkg.main ? bpd : pd);
