Resolution: fixed
Status: newclosed

Fixed in mainline,1686.

For the record: the bug can be reproduced by running /app/tester on any test except the logger ones (e.g. tester softfloat1).

The cause of the fault was that logger opens the log file (e. g. /log/tester) only when it is really needed – i. e. on first write to that file. Thus, if some application initializes logging but logs nothing (such as the softfloat1 test), on application exit the logger was closing NULL file stream.
