Thank you, too, Akira. With the patched version from Élie I now can 
compile fine and the formats are build.

Yes. Running now

valgrind -v --leak-check=full texlua luaotfload-tool.lua 2

results in the output here:

http://justpaste.it/2lq6

with the summary:

==29474== LEAK SUMMARY:

I guess ERROR is not good? …

I now tried again

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

but still it fills the whole memory up. The first time it stopped at the 
font Loma.ttf, so I blacklisted it, but now the last output I get is

luaotfload | db: loading font “/usr/share/fonts/TTF/Loma.ttf”
luaotfload | db: ignoring blacklisted font “/usr/share/fonts/TTF/Loma.ttf”

So maybe a font after this one is a problem? But as I don't see any 
system in the order in which the fonts are loaded, I cannot say which 
one is loaded next …

cheers
