The file is not corrupted, it's just that the recursion goes too deep
during reading. However, I don't think condition-case can reasonably
catch C stack overflow. As it is, recovering from C stack overflow at
all is a bit controversial, which is why we have the
attempt-stack-overflow-recovery variable which you can set to nil in
order to reliably segfault instead.
