/* For posterity, the issue here begins initial "char []" decl for
* s. This is a tentative definition and so a global was being
* emitted, however the mapping in GlobalDeclMap referred to a bitcast
* of this global.
*
* The problem was that later when the correct definition for s is
* emitted we were doing a RAUW on the old global which was destroying
* the bitcast in the GlobalDeclMap (since it cannot be replaced
* properly), leaving a dangling pointer.
*
* The purpose of bar is just to trigger a use of the old decl
* sometime after the dangling pointer has been introduced.
