Subject: Sema::ParseCastExpr() missing call to UsualUnaryConversions().
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=711602bb16b25fd29b951193a5f8bcc8d7def56e;p=clang

Sema::ParseCastExpr() missing call to UsualUnaryConversions().

The following case now works...

void empty(void * a ) {}

void test()
{
    unsigned char A[4];
    empty( (void *) A);
}

Thanks to Patrick Flannery for finding this...
