I have recompiled the JUCE DemoRunner from JUCE 5.4.0 on OS X 10.11.6 with Xcode 8.2.1 (and no modification in the source code).
I run DemoRunner,
click Browse Demos,
click OpenGLDemo.h (or any other item),
and the program quit with EXC_BAD_ACCESS (SIGSEGV)
This happens systematically with this sequence of commands.
I attach a copy of the crash report if that may help.
