Summary: Attached C++ file crashes clang in
SmallVectorTemplateBase code
Product: clang
Version: 2.8
Platform: Macintosh
OS/Version: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: C++
AssignedTo: unassignedclangbugs at nondot.org
ReportedBy: llvm-bugzilla at larrygritz.com
CC: llvmbugs at cs.uiuc.edu, dgregor at apple.com
The attachment has a repro case. The code is an excerpt from the Ptex open
source project -- http://ptex.us
I was running clang/llvm 2.8, direct from the svn repository. Running on OSX
(10.6).
tar xzvf test.tgz
cd test
clang -c PtexCache.cpp
The stack trace I get is:
