When I run valgrind, I get a reported error:

==734== 3,600 bytes in 90 blocks are definitely lost in loss record 8 of 10
==734==    at 0x4A05809: malloc (vg_replace_malloc.c:149)

==734==    by 0x4D3056: mt_cside_nio::InetAddressTest::testGetHostName() (InetAddressTest.cpp:55)

So I run with --gen-suppressions=yes and I get:

{
   <insert a suppression name here>
   Memcheck:Leak
   fun:_vgrZU_libcZdsoZa_malloc
   obj:*
   obj:*

   fun:getservbyport_r@@GLIBC_2.2.5
   fun:getnameinfo
   fun:_ZN12mt_cside_nio11InetAddress11getHostNameEPci
   fun:_ZN12mt_cside_nio15InetAddressTest15testGetHostNameEv
}

Which I add to a local file with <insert ... nane here> replaced.  When I rerun valgrind with --suppressions=local.filename, valgrind apparently ignores the file.

What am I doing wrong?
