Description:

PAREN_ARITHMETIC seems to be broken when bash-3.00 is compiled on IRIX:
e.g.

        $ bash-2.05 -c 'A=$(( 2 + 3 )); echo $A'
        5

        $ bash-3.00 -c 'A=$(( 2 + 3 )); echo $A'
        2: command not found

And, infact, there may be some form of off-by-one error here:

        $ bash-3.00 -c 'A=$(x(2+3)); echo $A'
        5

... so it looks as if the character immediately following the initial
opening bracket is dropped.

Repeat-By:

Compile bash on an IRIX machine using SGI's compiler suite
(MIPSpro 7.4.3m, in this instance).

Have yet to confirm whether bash compiled with GCC has the same problem...

Cheers,
