--- Comment #6 from Emil Velikov <emil.l.velikov at gmail.com> ---
Based of the backtrace there is no information if mesa/libglapi was build with
or w/o glx-tls. Following an IRC conversation it seems that the library is
built w/o glx-tls as i is missing the _glapi_tls_Context and
_glapi_tls_Dispatch symbols.

Perhaps they are different builds ? Either way it's good to attach the output
of $nm -CD --defined-only /usr/libx32/libglapi.so in this particular case.

Also please that the correct libraries are being picked up. This can be done
via something like:
 $LD_DEBUG=libs foo (startx) 2>ld_debug.log

Obviously none of these excludes that there is an actual issue with x32 and
glx-tls and/or that mesa silently ignores the flag on said platform ;-)
