For "in case", my dictionary has "If it happens that; if.", but I'm
sure that that is an incomplete definition.

I suppose that "in case" is a long-accepted shortening of "in the case"
or "in a case" and that "in case X, do Y" is a shortening of "in the/a
case of X happening, do Y".  This shortening can explain the above
warning, but another explanation is that it is a shortening of "In
cases of fire", which seems strictly correct to me.

This, and your original example, are not grammatically wrong, and are
fully sensical language.  The problem is with the meaning that the
language conveys.  (One hopes that it isn't the meaning the author meant
to convey, but that's a different issue.)  This is partly because we
understand "case" here to mean "an instance of a general case".  The
sentence is telling one what to do in a particular instance (ie, when
something happens), and that has a couple of problems.  1) When the case
happens, the advice doesn't help with this instance; there might not
even be a next one for which to use the advice.  2) The advice is
weasily; it tells you what not to do, instead of what to do, so that
running no programs follows the advice without solving the problem.
"In case you run out of memory, cry." has a much better "ring" to my
ear.  The sentences clearly need complete rewriting.

Usually, one can guess the intended meaning of of bad writing, but it
takes extra effort and it leaves one wondering if one guessed right.
Writers should think of their readers more and at least read what they
have written and do a bit of self-editing of the worst parts.

How one reads something depends a lot on one's tolerance and
imagination, but we should use little of either when discussing
the meaning of some writing.  The examples are not precautions,
as written, even if everyone is clever enough to find them so.
