[PULL 16/22] fuzz: disable leak-detection for oss-fuzz builds

Posted by Thomas Huth 5 months, 4 weeks ago

From: Alexander Bulekov <alxndr@bu.edu>

When we are building for OSS-Fuzz, we want to ensure that the fuzzer
targets are actually created, regardless of leaks. Leaks will be
detected by the subsequent tests of the individual fuzz-targets.
