[GRASS5] nviz crash on debian with tcltk8.4

GRASS GRASS developer
1

Hi,

finally getting around to looking at why NVIZ crashes on Debian/testing
when compliled with tcltk8.4. Here's the output of a gdb session, maybe
someone has ideas of where to look or what to try next.

GRASS 5.0.3 compiled with:
CFLAGS="-march=i686 -Wall -ggdb" ./configure \
  --with-tcltk-includes=/usr/include/tcl8.4 \
...

thanks,
Hamish

finally getting around to looking at why NVIZ crashes on
Debian/testing when compliled with tcltk8.4. Here's the output of a
gdb session, maybe someone has ideas of where to look or what to try
next.

GRASS 5.0.3 compiled with:
CFLAGS="-march=i686 -Wall -ggdb" ./configure \
  --with-tcltk-includes=/usr/include/tcl8.4 \

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)
