Source file that causes the error.
Hello everyone,
With a sufficiently large number of recursive template instantiations, clang++
(version 3.4 (trunk 185261), installed using Macports on OS X 10.8.4) crashes
with a segmentation fault, even when the "-ftemplate-depth-N" flag is used with
a large enough value of N.
$ clang++-mp-3.4 -std=c++11 -stdlib=libc++ -ftemplate-depth-10000 bug.cpp
clang: error: unable to execute command: Segmentation fault: 11
clang: error: clang frontend command failed due to signal (use -v to see
invocation)
clang version 3.4 (trunk 185261)
Target: x86_64-apple-darwin12.4.0
Thread model: posix
