--- Comment #1 from Phil Armstrong <phil@kantaka.co.uk> ---
Turns out the real problem is that FTL bundles a version of libstdc++ that the
DRI drivers won't link against.
It looks like the net result is that *no* DRI drivers (not even swrast) can be
loaded, and the Xserver dies when trying to invoke the first GLX call.
Here's the output of the program with LIBGL_DEBUG=verbose :
$ cat libgl_debug-output2.txt

If I remove the bundled libstdc++.so & use the system one then everything works
as expected.
Obviously this is still an Xorg crash bug though: the server ought not to crash
if a userspace program fails to load a glx driver!

Changed title to reflect underlying bug: I don't believe that the user should
be able to make the XServer process segfault by substituting the wrong
libstdc++ library when running an ordinary user process.
