Summary: Mserver crashes in gdk_atoms.mx
Initial Comment:
If I run the following XQuery query:
declare function int-check($ylist as xs:integer*) { $ylist };
int-check(distinct-values(1 to 3))
MonetDB exits with a segfault:
Program received signal SIGSEGV, Segmentation fault.

If I run the same query with debug=10 I get the following error message:
MAPI = [EMAIL PROTECTED]:50000
QUERY = declare function int-check($ylist as xs:integer*) { $ylist };
int-check(distinct-values(1 to 3))
ERROR = !ERROR: err:FORG0001: could not cast value from string to integer.
The reason is either the typing of fn:distinct-values or the implementation of
distinct-values. The former provides values of type untypedAtomic* whereas the
MIL implementation produces the more specific int*. The result is that the MIL
implementation tries to lookup values in the wrong container.
To come back to the real bug report: Mserver shouldn't segfault!
