--- Comment #2 from Reid Kleckner <rnk at google.com> ---
C++ exceptions are currently under development and not yet supported. You can
disable them in the VS project properties panel. Also consider adding
-D_HAS_EXCEPTIONS=0 so that the STL doesn't use them.

If your project doesn't use exceptions and you can't get things to work, feel
free to open more bugs for those issues.

I ran your test case and I get a different crash here:
While deleting: i8* %call.i62
Use still stuck around after Def is destroyed:  %.in = phi i8* [ %call.i62,
%invoke.cont26 ], [ %call.i63, %if.end18 ]
Assertion failed: use_empty() && "Uses remain when a value is destroyed!", file
..\lib\IR\Value.cpp, line 82
