            Bug ID: 79285
           Summary: new valgrind error in build
           Product: gcc
           Version: 7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dcb314 at hotmail dot com
  Target Milestone: ---

I just tried a gcc trunk build, under valgrind, and got this:

==19121== Invalid read of size 4
==19121==    at 0x9C9E3D: slide (hash-table.h:999)
==19121==    by 0x9C9E3D: begin (hash-table.h:476)
==19121==    by 0x9C9E3D: begin (hash-map.h:233)
==19121==    by 0x9C9E3D: release (symbol-summary.h:78)
==19121==    by 0x9C9E3D:
function_summary<ipa_node_params*>::~function_summary() (symbol-summary.h:57)
==19121==    by 0x7D2BA4: call (ggc-page.c:339)

Configure line was

../trunk/configure --prefix=/home/dcb/gcc/results.245021 \
    --disable-bootstrap \
    --disable-multilib \
    --disable-werror \
    --enable-checking=valgrind \
    --enable-languages=c,c++,fortran

The last time I did this, on 20170120, there was no such valgrind error.
