            Bug ID: 29270
           Summary: Signed integer overflow with DW_FORM_udata
           Product: binutils
           Version: 2.39 (HEAD)
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: binutils
          Assignee: unassigned at sourceware dot org
          Reporter: sevaa at sprynet dot com
  Target Milestone: ---

Test binary and source

Consider the debug info in the attached binary. If you execute "readelf
--debug-dump udata", you'll see the following line:


    <2f>   DW_AT_const_value : -9223372036854775808

The form of that attribute is DW_FORM_udata. It's unsigned and positive, the
minus is bogus.
