Yes, that was that.

Right now opera doesn't work yet (since it needs a few more libraries
currently unavailable) but the binary is executed successfully.

Hm this didn't work. It is crashing exactly the same way.
By the way the 32bit one's are not crashing.

The weird thing is that 64bit bash is not crashing, but 64bit ls or
date do. Should I submit a PR about this?

Okie. I'm going to test a few things now. I'll report my results.

Thanks to both of you,
