Comment 4 for bug 1743293

Here's my current workaround:
1. I built and installed the latest valgrind from source.
2. ~/.valgrindrc:
--sigill-diagnostics=no
--suppressions=/home/pi/.valgrind.supp
3. ~/.valgrind.supp:
{
  libarmmemv7laddr8
  Memcheck:Addr8
  obj:/usr/lib/arm-linux-gnueabihf/libarmmem-v7l.so
}
{
  libarmmemv7laddr4
  Memcheck:Addr4
  obj:/usr/lib/arm-linux-gnueabihf/libarmmem-v7l.so
}
{
  libarmmemv7laddr2
  Memcheck:Addr2
  obj:/usr/lib/arm-linux-gnueabihf/libarmmem-v7l.so
}
{
  libarmmemv7laddr1
  Memcheck:Addr1
  obj:/usr/lib/arm-linux-gnueabihf/libarmmem-v7l.so
}
