<pre>Downloaded <a href="https://github.com/apitrace/apitrace">https://github.com/apitrace/apitrace</a> from github and tried to build,
ollowing the instructions from their INSTALL file, using clang 3.4 (from Xcode
5.1) on my MacBook Pro
apitrace HEAD is 8d6c36d74ba9aefbc8c3618fc93dd4907a0dbf5e
<span class="quote">> cmake -H. -DCMAKE_BUILD_TYPE=RelWithDebInfo
> make -C build</span >
After 40 or so minutes, it was still chewing on the file glretrace_gl.cpp
Attaching lldb, I got the following stacktrace:

(I gave up after this, so I can't say how long it would have taken for the
build to actually complete)
Configuring cmake with -DCMAKE_BUILD_TYPE=Debug (disabling optimizations) makes
a build complete in a minute or so.</pre>
