Synopsis: Generic constraint with Rename that lists to Rename_pair elements crashes compiler
Description
A formal generic constraint that has an "empty" rename, such as
G -> STRING rename end
causes the compiler to crash. According to my reading of ECMA-367
(section 8.6.14), this should actually be a syntax error since a Rename_list
consists of one or more Rename_pair, not zero or more.
To Reproduce
Compile with attached classes and .ecf. Compiler crashes.
Problem Report Interactions
Bug is fixed in rev#68907. A syntax error is reported for empty rename clauses in the context of a constraint renaming. Thanks for reporting.
