Internal error with gawk 5.2.0

[Pascal Terjan]

This was reported to Mageia in
https://bugs.mageia.org/show_bug.cgi?id=30825 and I reduced it down to
the following code:

$ awk -e 'function foo(x)
{
        if (x == int(x))
                return (int(x) != 0)
}
BEGIN {
        foo(P["bar"])
}'
awk: cmd. line:4: fatal: internal error: file interpret.h, line 254:
unexpected parameter type Node_val
