Hi Philipp,

the output of

luaotfload-tool --update --force --verbose=5 --log=stdout

is available under


I stopped the program when suddenly the memory ran full. This happend at 
some step, it did not increase steadily during the whole process. Also, 
the CPU was at 100% from that point on. The output doesn't seem to 
report an error, does it?
