glibc-dl-cache.patch causes segmentation fault when _dl_get_origin fails (which should be harmless unless there is $ORIGIN in RUNPATH). I found this when running a dynamically linked executable as ‘init’, before /proc was mounted. There needs to be an origin != (char *)-1 check.

Somehow we forgot about this patch for a whole year, and it turns out I
stumbled upon the bug again just hours ago¹.

Now pushed to ‘core-updates’ as
edb8c09addd186d9538d43b12af74d6c7aeea082.

Thanks again, and apologies for the delay!

Ludo’.
