CRYPTO_set_mem_functions() always returns 0 because library
initialization already calls CRYPTO_malloc() and disables it:
#0 CRYPTO_malloc (num=num@entry=1168, file=file@entry=0x7ffff70ae02c

This doesn't happen in upstream OpenSSL or in Debian's OpenSSL.
Looking at the patches, this is caused by FIPS_drbg_init() in
openssl-1.0.2g-fips.patch:
+ if (!(dctx->xflags & DRBG_FLAG_TEST)) {
+ if (!FIPS_drbg_health_check(dctx)) {
+ FIPSerr(FIPS_F_FIPS_DRBG_INIT, FIPS_R_SELFTEST_FAILURE);
+ return 0;
+ }
+ }
I don't want any FIPS mode enabled though, so does it really even need
to call RAND_init_fips() then?
