For the record, these issues should be fixed in Guile 2.2.4: 533e3ff17 * Serialize accesses to submodule hash tables. 46bcbfa56 * Module import obarrays are accessed in a critical section. 761cf0fb8 * Make module autoloading thread-safe. ‘guix pull’ now defaults to 2.2.4, so we’ll see if indeed those crashes disappear.
