Bug ID: 19887
Summary: address_space casts causes assert
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: LLVM Codegen
Assignee: unassignedclangbugs at nondot.org
Reporter: jleidel at micron.com
CC: llvmbugs at cs.uiuc.edu
Classification: Unclassified
Created attachment 12575
--> http://llvm.org/bugs/attachment.cgi?id=12575&action=edit
Sample source file
The crash occurs when using non-standard address_space definition and casting
the result of return values from functions. The assert occurs in a different
module than elicited in bug 18549. Verified to fail at all optimization levels
Compiled using LLVM/Clang 3.4.1 release:
clang version 3.4.1 (...)
