Re: [HACKERS] [sqlsmith] crash in RestoreLibraryState during low-memory testing

This is the code in glibc-2.24 around the crash site:

,----[ glibc-2.24/elf/dl-load.c:442 ]
|       to_free = cp = expand_dynamic_string_token (l, cp, 1);
|
|       size_t len = strlen (cp);
`----

…while expand_dynamic_string_token will indeed return NULL on a failed
malloc.  Code in the most recent glibc looks the same, so I'll carry
this issue over to the glibc bugzilla then.

Sorry about the noise…
Andreas
