bug#16710: 24.3.50; emacs crash.

[Nicolas Richard]

Hello,

I was experimenting --with edebug-- a lisp infinite loop of recursive
calls, all wrapped in an ignore-errors, and got this crash. I could not
reproduce unfortunately, and in fact it doesn't seem to be related to
the lisp code I was looking at.

I don't know for sure, but it looks like something corrupted the data
structures that GnuTLS uses in each process and you noticed when the
process was destroyed (at that time, the data structures were already
invalid).

Can you replicate this?  It looks tricky, since you had an inactive TLS
connection in a process, if I'm reading the dump correctly.  Raising
`gnutls-log-level' *may* be useful, if you can replicate.

I couldn't reproduce, sorry. I'll set gnutls-log-level to 2 for a while,
in the hope I can "reproduce" after some more waiting.

Btw, I thought that TLS was not involved in the crash, because it
happens after this:

Do I read that wrong ?

I thought I saw a problem in the ASN.1 memory deallocation in GnuTLS but
I may have simply misunderstood the stack trace.  I'm not very good at
debugging Emacs crashes, sorry.

I don't want to praise myself, but I'd suspect that I am much worse than
you are about debugging anything. Anyway, I'll post again if I have
anything new.

So I see you reported several hard crashes with Emacs 24.3.50 (and one
with 25.0.50), which also lack an easily reproducible recipe.  Are you
still hitting these with more recent Emacs (25.3 or 26.1)?  I doubt
there is much hope of tracking any of these down by now otherwise.

That was one year ago.

Lacking any further information, maybe it is time to close this bug
report?

Ugh, mistyped the address.  Bug#16223 is now really closed.
