Bug#749830: closed by Sylvestre Ledru <sylvestre at debian.org> (Re: Bug#749830: /usr/bin/clang: clang++ crash when -g option used on template with pointer to member in signature)

[Ernie Ewert]

Just FYIŠ (I just tried this with the ³new² Xcode6-DP version of Clang++
and it does indeed work on that version.

/Users/ErnieE -> sudo xcode-select -s /Applications/Xcode6-Beta.app/
/Users/ErnieE -> clang++ -g -std=c++11 crash.cpp
/Users/ErnieE -> 

The version in XCode5 causes the same issue.

/Users/ErnieE -> sudo xcode-select -s /Applications/Xcode.app/
/Users/ErnieE -> xcodebuild -version
Xcode 5.1.1
Build version 5B1008
/Users/ErnieE -> clang++ -g -std=c++11 crash.cpp

In the close of the bug you mention that the version I am running isn¹t
³valid.²

I followed the directions here: http://llvm.org/apt/ for both Stable and
Development branches. Is there a ³better² version that I should acquire?
Am I missing something important? I wouldn¹t have filed the issue if
Xcode6 had been available and it had been shown to be fixed. I encountered
this with the Linux versions (3.4 and 3.5) installed via both the stable
and development branch versions as directed via the link above.

I am GLAD this is fixed, but I¹d like to know if there is a BETTER
approach I can follow so I don¹t ³waste² more time in the future. (Both
yours AND mine.) I am sorry if responding to this ³re-opens² the issue.
That is NOT my intent, but the instructions say to reply to the email.

I am ecstatic that this effort is happening and I hope that the project
doesn¹t get co-opted by any single vendor.

Thanks!
