Sorry, left out some info in the previous email.

The previous result was with any of the following added to the end of
XTRA_LDFLAGS in src.contrib/GMSL/NVIZ2.2/src/Gmakefile

-lpthread
-D_REENTRANT
-lpthread -D_REENTRANT


A previous version of Debian's tcltk8.4 worked with the -lpthread flag.


I just tried without any of those, and it crashes a bit earlier (never
make it to the menu). ... and recompiling with the extra flags 
again makes it crashes at startup now .. shrug.


Here's the gdb session for the crash when no extra compile flags are used:
(or now with the flags as well)
