           Summary: infinite loop in canonicaliseSymtab with ifunc symbol
    Classification: Unclassified
                OS: Linux
          Reporter: shiningxc@gmail.com
          Hardware: Debian testing
            Status: UNCONFIRMED
         Component: memcheck
           Product: valgrind

Running valgrind on a binary using gcc ifunc attribute result in an infinite
loop.
When running valgrind --trace-syscalls=yes --trace-symtab=yes ./a.out , the
following is printed endlessly:

canonicaliseSymtab: 0 symbols merged
overlapping address ranges in symbol table
            1:  TI 0x  400568 .. 0x  400572 (11)      test
            2:  T- 0x  400568 .. 0x  400572 (11)      resolve_test

Reproducible: Always

Steps to Reproduce:
Build the attached sample program and run it inside valgrind.
