Two quick tests:

-1-
On an old ubuntu 10  64-bit machine with PCRE, test "pcre-invalid-utf8-input" 
fails.
Log attached.
It is possible due to the test using "en_US.UTF-8" but the available locales 
are:

    $ locale -a | grep en_US
    en_US
    en_US.utf8

However, the 'get-mb-cur-max' does seem to accept "UTF-8":

    $ ./tests/get-mb-cur-max en_US
    1
    $ ./tests/get-mb-cur-max en_US.utf8
    6
    $ ./tests/get-mb-cur-max en_US.UTF-8
    6
    $ ./tests/get-mb-cur-max en_US.FOO-8
    (EMPTY)

It is possible this old machine is mis-configured, and if so - please ignore 
this failure.

Using "libpcre3" version "7.8-3build1" (from ubuntu 10 package).



-2-
On the same machine, which has 128 GB ram total, and 106 GB ram free:

    $ free -g
                 total       used       free     shared    buffers     cached
    Mem:           125         38         87          0          6         13
    -/+ buffers/cache:         18        106
    Swap:            9          3          6

The "big-match" test is still skipped with "not enough main memory to run the 
test" - which sounds a bit weird.
Log attached.
During the execution of the tests, the "grep" process consumed up to 4.0GB of ram (in the 
"RES" column of "top").


I'll be able to run the other test (on more OSes) a bit later.
