If you do not need vgdb (i.e. not using vgdb directly and/or the valgrind gdbserver and/or callgrind_control and similar), you can probably bypass the problem by giving --vgdb=no. Would be worth in any case to investigate what is wrong with the very relevant suggestions given by John.

By using "--vgdb=no", it works .Thank you.Chris--Original--From: "Philippe Waroquiers"philippe.waroqui...@skynet.be;Date: Fri, Nov 16, 2012 03:48 AMTo: "John Reiser"jrei...@bitwagon.com; Cc: "valgrind-users"valgrind-users@lists.sourceforge.net; Subject: Re: [Valgrind-users] Fw:valgrind on cortrex-a9 problemOn Thu, 2012-11-15 at 07:49 -0800, John Reiser wrote: ==15447== error 22 Invalid argument ==15447== error VG_(am_shared_mmap_file_float_valgrind) /tmp/vgdb-pipe-shared-mem-vgdb-15447-by-root-on-???
