Bug ID: 26596
Summary: clang crashes on x86_64-linux-gnu with message "Tried
to create a shift operation on a non-integral type"
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: LLVM Codegen
Assignee: unassignedclangbugs at nondot.org
Reporter: helloqirun at gmail.com
CC: llvm-bugs at lists.llvm.org
Classification: Unclassified
The current clang trunk crashes when compiling the following test case on
x86_64-linux-gnu in both 32-bit and 64-bit modes.
It might be a regression from 3.3.
