Hi,

the test fails for some reason, relatively rarely (20 per 100 invocations). I could not find the why, so I'm just posting the logs below with the full log attached.

The test has been failing here for at least a year (the logs below done with v2.25.1).

I have a config.mak:

    USE_LIBPCRE2=YesPlease
    OPENSSL_SHA256=YesPlease

    CFLAGS += -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=1
    CFLAGS += -fstack-protector-strong
    CFLAGS += -fpie
    LDFLAGS += -z relro -z now
    LDFLAGS += -pie

There local modifications, but none in the core core (small customizations in gitk).

The file system where the test is run on is an ext4 volume (an old, but still usable ssd). The kernel is an v5.5.3. Debian without systemd. Not a container. Not a VM.
