The libz compression library on SystemZ by default makes use of the platform's hardware-accelerated compression facility. This is much faster than the regular software implementation, but often results in slightly different outputs. This causes failures with the compressed-debug-level test case. To fix this, set the DFLTCC environment variable to zero while running tests on SystemZ, which prevents use of hardware compression and falls back to the software implementation.
