Description Zhao Shujing 2007-07-31 02:11:38 UTC 
When enter a value that is too smaller than the lastKnown value at fromBox,
frysk would be hang. For example, changing the value from 3336ac33a0 to
3336ac0000 causes a hang. The only way to stop frysk at this point is to suspend
the process, and kill it. When enter a value a too bigger than the lastKnown
value at toBox, it causes a hang too.

This also applies to the disassembly window.
Comment 2 Zhao Shujing 2007-07-31 08:02:26 UTC 
There is also no check about whether the memory address is accessible for the
application.

        * gladedir/memorywindow.glade: Change the top text "current program
        counter" to segment combox. Fixes #4614 and #4619.
        * gladedir/disassemblywindow.glade: Ditto.
        * memory/MemoryWindow.java: Added handling for segment.
        Added warning dialogs when the address can't be accessed and when the
        symbol is not in current context.
        Added handling when too many rows be added. Fixes #4870.
        * disassembler/DisassemblyWindow.java: Ditto.
