#1039: i.group segmentation fault using full path name
----------------------+-----------------------------------------------------

Type: defect | Status: closed

Comment:
The error is related to the I_location_info(title, argv[0]) call before
line 112 and the size of the title buffer. The consequence is a buffer
overflow resulting in a segfault.
The I_location_info() function is implemented quite unsafe using sprintf
without checking the buffer length. It is always a bad idea to fill a
buffer with an unknown length. I have fixed this in svn [41880] and
removed the unused I_location_info() call from i.group.
It seems to me that I_location_info() is not used by any imagery module?
Could it be removed?
