_______________________________________________________
Details:
This bug covers the situation described in patch #6895 and bug #27235.
I've added an alternative patch for this bug and a test case for
regressions.
Quote from patch #6895:
"Situation:
a = malloc(10);
b = malloc(10);
free(b);
Now there is a free chunk at the end of the used area of the heap.
b = malloc(20);
The new request can not be satisfied by any free chunk, therefore the used
area needs to be expanded."
