In the file config.c on line 1774:
a.group = -(fearea.info.group + 1);
negative value is assigned to unsigned variable.
All code chunk:
/* ... and set an invalid (negative) group handle. Later, we will
register all Fastecho groups that have been marked as used, and then
iterate the area array to set the correct group handle for all areas
that have a negative group handle. */
if (SW->areafilegroups)
a.group = -(fearea.info.group + 1);
else
a.group = 0;
This is somewhat old; will need to verify if the issue is still present and/or has already been resolved.
