<div>
<pre>If the static function createFree in IR/Instructions.cpp (apprx. line 481) is
called with a basic block in which the call to free should be placed, it might
not end up there.
The code which reads (git: 79e3fb53d618d12e239275ef055200bbd6f8253e):
if (Source->getType() != IntPtrTy)
PtrCast = new BitCastInst(Source, IntPtrTy, "", InsertAtEnd);
Result = CallInst::Create(FreeFunc, PtrCast, "");
should be changed to:
if (Source->getType() != IntPtrTy)
PtrCast = new BitCastInst(Source, IntPtrTy, "", InsertAtEnd);
Result = CallInst::Create(FreeFunc, PtrCast, "", InsertAtEnd);</pre>
