Parsing this particular csharp content causing Fatal Error

[chengtianxing]

Passing the following c-sharp code content in Parser.parseString() causes fatal error in JVM, which appears to be due to the "SIGSEGV" error on the C side:

Perhaps you are using tree-sitter-c-sharp? I believe that has a scanner.c file.

The 3rd item in this PR might help in getting things to work.
