 Hi,

 Debian's run of the Cpp check tool automatically found a number of C-code
 errors (or
 potential errors) which need to be reviewed by hand. See grass-dev ML
 thread
 of 13 Jan 2011.

 about:
  http://www.linuxjournal.com/content/daca-could-mean-less-bugs-debian
 the list of probably-bugs in the 6.4.0 C/C++ code:
   http://qa.debian.org/daca/cppcheck/squeeze/grass_6.4.0~rc6+42329-3.html
 CLI analysis program (not Debian specific):
   http://cppcheck.wiki.sourceforge.net


 I have split those 154 hits into 16 classes, and will report each class in
 an individual bug report.


 Run against releasebranch6_4 r42329 (including all patches up to, but not
 beyond, 6.4.0-final)

 This bug report is for: '''Array index is out of bounds'''

  * ./raster/r.flow/precomp.c:154 [error] - Array index -1 is out of bounds
  * ./raster/r.flow/precomp.c:158 [error] - Array index -1 is out of bounds

 Modules: r.flow, v.in.dwg
