Bug ID: 23678
Summary: crash in optimizer
Product: clang
Version: 3.6
Hardware: Macintosh
OS: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs
Assignee: unassignedclangbugs at nondot.org
Reporter: mark at artillery.com
CC: llvmbugs at cs.uiuc.edu
Classification: Unclassified
Just found a crash in clang that seems to be in the optimizer. The crash
reproduces at -O2 and -O3, but not at -O1. It also reproduces if the opt tool
is run on a .bc file emitted by the compiler without optimizations.
Here's the trace:
