Hello,

i checked the sorces of libX11-1.1.5 with static code analyis tool cpppcheck.
It brought up an issue in file libX11-1.1.5/modules/om/generic/omGeneric.c at
line 618. 

Cppcheck has the following output:

[libX11-1.1.5/modules/om/generic/omGeneric.c:618]: (error) Overlapping data
buffer rotate_font_ptr

Take a look at the sourecode (line 618):

sprintf(rotate_font_ptr, "%s-%s", rotate_font_ptr, fields[field_num]);

Indeed, cppcheck is right.


Best regards

Ettl Martin
