Subject: bug#72605: [core-updates] jemalloc test failures on aarch64-linux
Date: Tue, 13 Aug 2024 18:15:35 +0200

The ‘test/unit/psset’ test of jemalloc 5.3.0 fails on ‘core-updates’ for
aarch64-linux, but only on the Honeycombs (I retried several times) and
not on the Overdrive:

(From <https://ci.guix.gnu.org/build/4573316/details>.)

I wonder if this has to do with large page sizes (‘--with-lg-page=14’
added in commit c2c12037eea880f935f225b9166e59e9c19be883).

It echoes this upstream bug report:

  https://github.com/jemalloc/jemalloc/issues/2408

However, on both overdrive1 and pankow, I get:

--8<---------------cut here---------------start------------->8---
$ guix shell glibc -- getconf PAGESIZE
4096
--8<---------------cut here---------------end--------------->8---

Any idea what other factors might be relevant?
