<pre>The commit r313729 introduced a new `!Old || Old->getCachedLinkage() ==
D->getCachedLinkage()' assertion failure that happens in the following cod e
sample:
extern "C" {
typedef struct {
int x;
} *ReturnStruct;
ReturnStruct foo(int s);
}
ReturnStruct foo(int s)
{
}
This is similar to existing bugs like
