Subject: lib-compression: bench-compress - Ensure we have both istream and ostream constructor
X-Git-Tag: 2.3.17~118
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=85e65dd58a1d2f8f7c7f47556c4c22bcea9d9df2;p=thirdparty%2Fdovecot%2Fcore.git

lib-compression: bench-compress - Ensure we have both istream and ostream constructor

After 6e5ae5ef0f0f31acd7bde0db53980a708c81eced we have read-only compression
mechanism, that leads to null pointer crash in bench-compress.
