Subject: bug#31878: Module autoloading is not thread safe

From: [email-masked] (Ludovic Courtès)
Date: Mon, 18 Jun 2018 11:43:17 +0200

Hello,

The backtrace below (from Guile 2.2.3) shows the Guix multi-threaded
module compilation code crashing with an incorrect module resolution
failure (incorrect because the module does exist.)

I believe this comes from the fact that ‘autoloads-done’ and related
alists in (ice-9 boot-9) are manipulated in a non-thread-safe fashion.
Notice that a couple of threads in the backtrace are effectively
running:

  (member x autoloads-done)

Thanks,
Ludo’.
