Comment(by hamish):

 Hi, just tested 6.5svn r42750 nightly build on XP. And I'm back to the
 original error message & exit code 3:
 {{{
 #spearfish
 g.region rast=elevation.10m
 r.terraflow elev=elevation.10m ...

 Assertion failed: nrows * ncols == str->stream_len(), file grass2str.h,
 line 144
 }}}

 the left over .../Temp/STREAM_a02688 file is 10,619,208 bytes.

  * (and .../Temp/ is full of 100+ old tmp*.ppm files at a MB each... :-/
 new ones even after exiting the wxGUI cleanly. now that I look, it's the
 same in /tmp/ in linux)

 This application has requested the Runtime to terminate it in an unusual
 way.

 the `length = 9175040` reported by the debug message jumps around every
 time I run it, sometimes it's 0, sometimes its ~550000 or so.

  * also often it dies just after the "stats.out file found, renaming."
 message with error code 1. `rm stats.out*` at the msys prompt gets it
 working again.
