Description Mike Cvet 2006-10-03 17:02:23 UTC

Opening the SourceWindow on a process with two threads and debuginfo gave me
this on x86_64:

java.lang.NullPointerException

        * hpd/ExprSymTab.java (put): Check that the die has a type.
        (get): Likewise.

(Added expression dejagnu testing to check for regressions)
