Bug #: 15120
Summary: Assertion failed: (!From.isInvalid() && "Implicit
field reference cannot fail")
Product: clang
Version: trunk
Platform: PC
OS/Version: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: Frontend
AssignedTo: unassignedclangbugs at nondot.org
ReportedBy: lakseru at gmail.com
CC: llvmbugs at cs.uiuc.edu
Classification: Unclassified
Created attachment 9947
--> http://llvm.org/bugs/attachment.cgi?id=9947
Source that makes clang crash.
I got this while compiling some production code (which in retrospect contained
c++ errors), so the original source was very big. I tried slimming it down with
delta, but it got unreadable (nevertheless I attached that source).
Version of clang:
$ ~/Documents/Code/build/Debug+Asserts/bin/clang -v
clang version 3.3 (trunk 170991)
Target: x86_64-apple-darwin11.4.2
Thread model: posix
Backtrace:
joshua at n040005:~/Documents/Code/ClangBug$ ./main-lFe7mm.sh
main-lFe7mm.cpp:15:55: fatal error: expected class name
template <class _Tp> struct __is_void : public false_type {

It also crashes in the Release build of this clang.
Crash was gone after fixing our code, so it may be not so relevant...
