This differs :
llt('9 ', '10') : F
llt(' 9', '10') : T
Test : changing format '(a,i0)' to e.g. '(a,i2)'
$ a.out
Sorting ...
Result:
1
2
3
4
5
6
7
8
9
10
String = 1
String = 2
String = 3
String = 4
String = 5
String = 6
String = 7
String = 8
String = 9
String = 10

Confirmed. Closing as INVALID?

Let me clarify:
the STRING "String = 10" should come after the STRING "String = 1 ". It is not
a matter of the numbers inside. If you compare these strings with LLT(), you
will see this.

I have instrumented the test and found that 'String = 10 ', which at
the first position, is compared only once at the first call to quick sort, but
not for the other invocations of array(1:j). I am unable to understand why.

--- Comment #5 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
Apparently there is a nasty bug somewhere: if I sort
'String = 2 '
'String = 9 '
'String = 8 '
'String = 7 '
'String = 6 '
'String = 5 '
'String = 4 '
'String = 3 '
'String = 10 '
'String = 1 '
I get
String = 2
String = 1
String = 10
String = 3
String = 4
String = 5
String = 6
String = 7
String = 8
String = 9

--- Comment #6 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
The problem is not limited to strings. If I add the following lines
array(1)%value = 2
array(9)%value = 10
write( string_array(1)%value, '(a,i0)' ) "String = ", 2
write( string_array(9)%value, '(a,i0)' ) "String = ", 10
the initial values are
2 'String = 2 '
9 'String = 9 '
8 'String = 8 '
7 'String = 7 '
6 'String = 6 '
5 'String = 5 '
4 'String = 4 '
3 'String = 3 '
10 'String = 10 '
1 'String = 1 '
and the "sorted" ones are
2
1
3
4
5
6
7
8
10
9
String = 2
String = 1
String = 10
String = 3
String = 4
String = 5
String = 6
String = 7
String = 8
String = 9

Yes, I can confirm this - I also tried with the Intel Fortran compiler and that
sorts the integers and strings in the way one would expect.
