--- Comment #2 from Tom de Vries <vries at gcc dot gnu.org> ---
OK, the test run was on top of a few proposed patches, which moves the
dwz_with_low_mem call into a separate process, such that we only see the
problem later, which explains why we don't see dwz_with_low_mem in comment =
0.

On trunk, we do get dwz_with_low_mem instead of dwz:
...
Direct leak of 432 byte(s) in 6 object(s) allocated from:
    #0 0x7f8d6a37d6d8 in __interceptor_calloc (/usr/lib64/libasan.so.4+0xdc=
6d8)
    #1 0x475e34 in htab_try_create /home/vries/dwz/dwz.git/hashtab.c:164
    #2 0x44c610 in build_abbrevs /home/vries/dwz/dwz.git/dwz.c:11230
    #3 0x44ee00 in compute_abbrevs /home/vries/dwz/dwz.git/dwz.c:11510
    #4 0x46f07c in dwz /home/vries/dwz/dwz.git/dwz.c:15396
    #5 0x4748f5 in dwz_with_low_mem /home/vries/dwz/dwz.git/dwz.c:16274
    #6 0x474eb5 in dwz_files_1 /home/vries/dwz/dwz.git/dwz.c:16343
    #7 0x47570c in dwz_files /home/vries/dwz/dwz.git/dwz.c:16427
    #8 0x475a6f in main /home/vries/dwz/dwz.git/dwz.c:16468
    #9 0x7f8d69cf2349 in __libc_start_main (/lib64/libc.so.6+0x24349)
...

Anyway, looks like the problem is not specific to low-mem, adapting summary.
