    Test Suite VSU version 4.1.1
    Test Identification base/regcmp 26
    Problem Summary TSD4U.00190 This test may fail because memory is being freed twice.
    Problem Text
    In the regcmp test case 26
    when Begin=0176 the inner loop which contains the regcmp is not entered
    because End==Begin+1==0177. This leads to the situation that at the end
    a free(cresults) is done on an address that has been freed during the
    loop iteration when Begin=0175. It seems that the free should be in the
    inner loop and the free on already free space is a testsuite deficiency.
    On our implementation a free on an already freed space leads to a
    segmentation violation, which is conformant with the specification:
    Any use of a pointer that refers to freed space causes undefined behaviour.
