Problem Summary TSD4U.00201 This test may fail due to memory management logic errors.

Problem Text
In TSD4U.00170, if malloc failed and use sbrk() to create a faked address, free
this faked allocated address cause SIGSEGV problem. However, this free also
cause different undefined results because memory corruption.

If run AF_INET SOCK_STREAM and AF_UNIX SOCK_STREAM both, because first run
AF_INET SOCK_STREAM and did free(), run AF_UNIX SOCK_STREAM got 2 different
result.
1. child socket hang and parent time out cause UNRESOLVED result.
2. child socket hang, parent timeout and got SIGSEGV, cause FAIL result.

Beside, the test case may cause DOUBLE free() if it run more than one socket
type (AF_INET/AF_UNIX SOCK_STREAM/SOCK_DGRAM).

We did a test, if no this invalid free(), run this test case can get 'PASS'
result.
