             Bug #: 52312
           Summary: grokfndecl: valgrind problem
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal

        ReportedBy: dcb314@hotmail.com


I just tried to compile the file
gcc/testsuite/g++.dg/cpp0x/udlit-nounder-neg.C under valgrind on trunk
dated 20120216 on an AMD x86_64 box.

Valgrind said

==11414== Conditional jump or move depends on uninitialised value(s)
==11414==    at 0x4C442F: grokfndecl(tree_node*, tree_node*, tree_node*,

No special flags required.
