## #55590 — Ferenc Kovacs — 2011-09-22T20:34:24+00:00

I just stumbled upon on this test as it timed out for me(my test vm
started swapping, so run-tests.php terminated after 60 sec).
I think it would be good if we could somehow check the available ram,
and skipif if it isn't enough, and I think we could also save off an
str_repeat call:
each str_repeat call allocates 512M of ram, so the 5th call will never
happen when the bug is present, as it would allocate a little more
than 2.5G ram.
the test could be modified having a memory limit of 2100M and removing
the sixth str_repeat call and the line '5' from the expect output.

btw: what do you think about adding a memory_get_available() function:
