I think I have resolved the issue. I'd guess it is a namespace problem.
I had a keyword "reverse" as well as the function "reverse()".
This is using the default compiler options (i.e. I am not setting anything).

So if you start of a fresh IDL, and type
IDL> .run namespacecrash

% Compiled module: NAMESPACECRASH.

% Compiled module: $MAIN$.

0.000000 1.00000 2.00000 3.00000 4.00000

1 1 1 1 1

Here is the routine:

function namespacecrash,array,reverse = reverse

if keyword_set(reverse) then begin
array = reverse(array)
endif

return,array
end

array = findgen(5)

print,namespacecrash(array)

print,namespacecrash(array,/rev)
end

My results are:
% Compiled module: NAMESPACECRASH.

% Compiled module: $MAIN$.

IDL> .GO

0.000000 1.00000 2.00000 3.00000 4.00000

1 1 1 1 1

IDL> help,!version,/st
