read_init() allocates el_read.
However, it is not freed in read_end() (which is called by el_end()).
Run with LeakSanitizer.

==27324==ERROR: LeakSanitizer: detected memory leaks

Direct leak of 32 byte(s) in 1 object(s) allocated from:
    #0 0x7ffff6efbe50 in malloc (/lib64/
    #1 0x7ffff5c25ac2  (/lib64/

SUMMARY: AddressSanitizer: 32 byte(s) leaked in 1 allocation(s).

(gdb) b *0x7ffff5c25ac2
Breakpoint 3, read_init (el=el@entry=0x61a00001d480) at read.c:88
88		if ((el->el_read = el_malloc(sizeof(*el->el_read))) == NULL)

(gdb) p sizeof(*el->el_read)
$1 = 32

Add in read_end() before its end:


(The following can be removed:
el_read->macros.macro = NULL;)
