When setting break point at UnitConverter::combine or UnitConverter:1880, the following error occurs: Dwarf Error: Cannot find referent at offset 64471289. I am willing to provide you the executable. Russell
EDK currently doesn't support the ia64 platform. This sounds like either a gcc or gdb bug (depends on whether or not gcc is emitting bad debug information or gdb is processing it wrong). I'd submit a bug report to either of those two groups.
