I see this fault when compiling the first grammar example below:

The problematic grammar:
grammar x_grammar;
#token h_digits { <:i[0-9a-f]>+ }
#token h_digits { <[0-9a-f]> }
token TOK_CONSTANT {
#<h_digits> ( : <h_digits> )**{1..15}
<h_digits> : <h_digits>
}
This example is extracted from a larger grammar to demonstrate the
problem. When I simplify it further by removing the commented-out
lines, e.g.:
grammar x_grammar;
token TOK_CONSTANT {
<h_digits> : <h_digits>
}
PGE compiles it successfully!
