>Description:
This test involves computing, e.g., this Argon2 hash: $argon2id$v=19$m=65536,t=2,p=1$c29tZXNhbHQ$C4TWUs9rDEvq7w3+J4umqA32aWKB1+DSiRuBfYxFj94", "differentpassword

The m=65536 parameter means that it uses 65536 KiB of working memory.

The sparc testbed runs with 64 MiB of RAM.  (The hpcmips is configured with even less, 48 MiB, but it hasn't worked in a while.)  This is not enough -- without some swap space, anyway -- to complete the test.
>How-To-Repeat:
cd /usr/tests/lib/libcrypt
atf-run t_crypt | atf-report
>Fix:
1. Split the test into several test cases, low-memory and high-memory.
2. Declare the memory requirement for the high-memory ones: atf_tc_set_md_var(tc, "require.memory", "64M");
