[Pkg-javascript-devel] Bug#950483: nodejs: Segmentation fault in v8::internal::compiler::(anonymous namespace)::MayAlias

[Tim Düsterhus]

Package: nodejs
Version: 10.15.2~dfsg-2
Severity: important
Tags: patch upstream

Dear Maintainer,

   * What led up to the situation?

I'm running a nodejs based application server.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

Specifying `--noturbo_load_elimination` works around this issue.

   * What was the outcome of this action?

The process crashes using a segmentation fault every roughly 30 minutes
to 1 hour. The segmentation fault happens within v8's optimizing
compiler.

   * What outcome did you expect instead?

I expected it not to crash.

I've already reported this issue upstream in nodejs' GitHub issue tracker:

https://github.com/nodejs/node/issues/31484

The upstream maintainer proposed a patch that I could verify fixing my
issue using the upstream tarball of nodejs 10.15.2 (i.e. the Debian
Buster version without any Debian specific patches):

https://github.com/nodejs/node/pull/31613

I'm filing this Debian bug to request a backport of this patch to Debian Buster.

Best regards
Tim Düsterhus
