Comment 1 Mike Cvet 2007-06-08 14:51:42 UTC

I can reproduce with FryskGui as well.

Comment 2 Phil Muldoon 2007-06-14 19:33:39 UTC

Confirm same results with a corefile backtrace

Comment 3 Nurdin Premji 2007-06-15 17:37:04 UTC

Fixed

	* DwarfDieFactory.java (loadDies): Call System.err.println 
	for each class, avoids ecj optimizing out these classes.
