After drawing the region on image I click to the Analyze region Menu, I get this error message WARNING:PREPARE_SIGNATURE: DATA ERROR (CLICK MOUSE TO CONTINUE). It seem that all the regions that I chose before now disappear. I try again with GRASS57, the result is also the same. Can you solve this problem for me? Thank you very much,

I traced this back to INAME_LEN being changed from 30 to 256 in
include/imagery.h.

This makes lib/vask/V_ques.c: V_ques() bomb out starting at line:

if ((length <= 0) || ((length + col) > 80)) ...

where the variable 'length' is passed in as INAME_LEN.

The program keeps running until it dies with a floating point exception.
