Comment 1 Oliver Kellogg 2012-02-12 21:34:57 UTC

Could you attach Java code that triggers the crash?
Thanks.

Comment 2 thomas 2012-02-12 22:22:32 UTC

A minimized sample:

public class Bug{
	public static <T> void walk(){
		jump();
	}

	public static <T> Class<T> jump(){
		return null;
	}
}

Comment 3 Oliver Kellogg 2012-02-13 07:25:57 UTC

SVN commit 1279716 by okellogg:

parseStmt(): Check for keyword == "<" and skipToClosing('<') short before
expecting `keyword' to be a type name. If `keyword' is then not a type name,
avoid accessing m_klass in the error message if m_klass is NULL.

Thanks.
With r1279716 at least it does not crash anymore but it's probably not perfect yet.
I'll test some more before setting this to FIXED.

Comment 5 Oliver Kellogg 2012-02-13 18:25:12 UTC

Yup, r1279716 did the trick.
