Comment (by neteler):

 New patch uploaded with bugfix only (so back to /var/tmp/ default). The
 bug is AFAIK here:

 [source:grass/branches/develbranch_6/raster/r.terraflow/main.cc#L179]

 The assignment to opt seems to fail:
 {{{
   opt->mem = atoi(mem->answer);
   opt->streamdir = streamdir->answer;
   G_debug(0,"DEBUG streamdir %s",streamdir->answer);
   G_debug(0,"DEBUG opt %s",opt->streamdir);

 leads to

 GRASS 6.5.svn (spearfish60):> r.terraflow elev=elevation.10m \
     filled=elevation10m.filled     dir=elevation10m.mfdir \
     swatershed=elevation10m.watershed     accumulation=elevation10m.accu \
     tci=elevation10m.tci d8cut=500 memory=800
 stats=elevation10mstats.txt\
     STREAM_DIR=/tmp  --o
 ...
 D0/0: DEBUG streamdir /var/tmp/
 D0/0: DEBUG opt /var/tmp/
 ...
 }}}

 Confusing... Interestingly, if I use (note the d typo):

 {{{
 r.terraflow elev= ... STREAM_dDIR=/tmp
 }}}

 the module does not fail. Apparently parse_args() fails?
