nanogui: Thread: segfault in example binaries

Hi,

Just tried mterm and microwindow linux binaries I downloaded from
www.microwindows.org (actually from ftp://microwindows.censoft.com/pub/microwindows/LinuxExamples)

They segfault on my machine cause I got the framebuffer using 16-bits depth. If
I switch to 8-bits, it works fine, although the pointer of the mouse won't
move.

strace attached.

Thanks.

Please cc me, i'm not subscribed.

Hmm...  The example binaries are not built from the latest source
release.  I would suggest that you compile up from source and
see whether this is still a problem.
