The MALLOC_CHECK_ environment variable is used in malloc(3), to decide which implementation use. It could have 4 different values:
- MALLOC_CHECK_ is not set: When MALLOC_CHECK_ has not been set, then malloc(3) have the usual behavior, nothing special happens.
- MALLOC_CHECK_ = 0: All errors are silently ignored.
- MALLOC_CHECK_ = 1: On error, a diagnostic message is printed on stderr.
- MALLOC_CHECK_ = 2: On error, abort(3) is called without a diagnostic message.
- MALLOC_CHECK_ = 3: abort(3) is called, and a diagnostic message is printed.
startkde script set this variable to 2 in trunk, so maybe you'll have crashes because of that.
Notice that, the faster implementation is which is used when MALLOC_CHECK_ is not defined.
