[Bug fortran/18475] New: Crash on a print

            Bug ID: 18475
           Summary: Crash on a print
           Product: gdb
           Version: 7.9
            Status: NEW
          Severity: normal
          Priority: P2
         Component: fortran
          Assignee: unassigned at sourceware dot org
          Reporter: at_gdb at mathalacarte dot com
  Target Milestone: ---

While running ddd 3.3.12 with gdb 7.9.1 on a Fortran program I encountered
this:

(gdb) p y(nv1:lrow)
cp-namespace.c:341: internal-error: cp_search_static_and_baseclasses: Assertion
`name[prefix_len + 1] == ':'' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.

This is a bug, please report it.  For instructions, see:
<http://bugs.gentoo.org/>.

At this point nv1 and lrow can both be printed and nv1=8 and lrow=9
p y(8:9) prints results just fine.

Just tried a similar thing with a different variable having a name ending in 1
and got the same kind of crash.  Perhaps things are grouped like <nv><1:...
instead of <nv1><:...?

--- Comment #1 from Mike Frysinger <vapier at gentoo dot org> ---
can you post a reduced fortran test case ?  that helps us track down and
include regression tests.

what target is this (i.e. your $CHOST) ?
