Hello all,
using DirectFB 1.4.15 and DirectFB-examples-1.2.0 from buildroot-2011.11
on an ARM926EJS-based platform "df_dok --draw-string" is crashing with a
"Floating point exception" for me.
The offending code can be found in draw_string() and
draw_string_blend(). For my system, "SW" (screen width) is 320 and by
lucky chance "stringwidth" is 320 as well.
The calculation "myrand() % (SW-stringwidth)" then produces the floating
point exception, because (SW-stringwidth) is 0 ...
The attached patch for DirectFB-examples-1.2.0 changes the code so that
it checks if (SW-stringwidth) is> 0 and if not, uses 0 instead.
The bug is present in the Git version of df_dok as well.
Your patch is finally applied, thanks!
