Extended Description

gcc version 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)

Attaching logs and the .ii file.

[lattner]

llvm-gcc is obsolete, please upgrade to clang. If you're experiencing this with an apple compiler, please file a radar at http://bugreport.apple.com/

[llvmbot]

Ah, well, it happens with clang as well, and I filed a radar as well.

I just filed here figuring you guys would care. Do you not?

[llvmbot]

No-one cares much about llvm-gcc, but people do care about clang.
I was unable to reproduce here (on linux): both clang and llvm-gcc rejected
the .ii file with an error.

[llvmbot]

What is the error?

What's the version info? I see:

htf-mbp:~ htodd2$ clang++ -v
Apple clang version 2.1 (tags/Apple/clang-163.7.1) (based on LLVM 3.0svn)
Target: x86_64-apple-darwin11.0.0
Thread model: posix

[llvmbot]

$ clang -v
clang version 3.0 (trunk 136459)
Target: x86_64-unknown-linux-gnu
Thread model: posix

This PR is mislabeled. The Xcode 4.1 llvm-g++ compiler does not segfault but produces legal compile time errors...

For reference, the radar is rdar://problem/9864384. For some reason, the .ii file didn't get attached to the radar but I'll grab it from the attachment here.

[lattner]

No we don't, llvm-gcc is obsolete as far as llvm.org goes. Thank you for filing the radar!

[llvmbot]

The actual problem is my misunderstanding. The problem occurs in clang++, and I thought the community developed version was currently llvm-g++.

Should I re-open this correctly or should I just change the compiler and add the correct log file?

Thanks.

[llvmbot]

errors from clang++
this is when I run clang++ with no flags on the .ii file.

[llvmbot]

This segfault doesn't exist in current llvm svn for clang but produces errors instead...

Trying to change to the right project.

This failure does exist in release clang++ from llvm 2.9....
