            Bug ID: 36764
           Summary: lifetime.end requires the size to be an i64
           Product: libraries
           Version: 5.0
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: Interprocedural Optimizations
          Assignee: unassignedbugs at nondot.org

IRBuilderBase::CreateLifetimeEnd generates the title's error message in a
exception, when asserting that Size's type must be equal to getInt64Ty().

CreateLifetimeEnd is called by InlineFunction's llvm::InlineFunction. (roughly
line 1868).

I suspect the assertion fails because Size was created within the pointer's
context, e.g., Type::getInt64Ty(AI->getContext()) and therefore will not
successfully match the equivalent type that CreateLifetimeEnd obtains from the
global context.

My suspicion was confirmed when I changed my compiler from using a created
context to using the global context, and the problem went away.
