Hi,

This problem occurs with fontgorge-20090408, compiled, and with X
and without. With fontgorge-20080429 is working well.

Execution of script by using Valgrind:

valgrind --tool=memcheck ./stripttf.ff uming.ttc zh.ttf $(sort -n zh | uniq)

I get output:

==10707== Process terminating with default action of signal 11 (SIGSEGV)
