Lately, I see this quite often when I play widelands:
widelands: ../src/graphic/texture_cache.cc:79: void TextureCache::drop(): Assertion `it != entries_.end()' failed. Aborted (core dumped)
I had a look at this texture_cache.cc, however, it was the first time I looked into widelands source code, so I can't really tell what's going on. At first glance, I don't see an obvious mistake.
Do you have any insights?
