           Summary: [8.0 Regression] FAIL:
                    gdb.ada/info_locals_renaming.exp: info locals (GDB
                    internal error)
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal

  Target Milestone: ---

Diffing current master (7.12.50.20170215-git) gdb.sum against a log from
20161209, I see this regression:

 -PASS: gdb.ada/info_locals_renaming.exp: compilation foo.adb 
 -FAIL: gdb.ada/info_locals_renaming.exp: info locals (GDB internal error) 

gdb.log shows:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
(gdb) info locals
gv = /home/pedro/gdb/mygit/src/gdb/value.c:372: internal-error: int
value_bits_any_optimized_out(const value*, int, int): Assertion `!value->lazy'
failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n) FAIL: gdb.ada/info_locals_renaming.exp:
