Closing: works for iuso after removing -Os (compiler optimization bug)

I found out that this bug is caused by the -Os compiler option. All is well after I removed that from CFLAGS. Perhaps LASH's Makefile should take this into account.

Here is a valgrind log of a client that was run during the crash.

lashd segfaults when a client is run. I tested it with muse (0.8.1), lash_synth, and lash_simple_client.

The client reports:
lash_comm_recv_run: recieved unknown event of type -1209691916.
lashd exits saying:
loader_run: server closed socket; exiting
Segmentation fault (core dumped)

Kernel is 2.6.17.7 with the realtime-lsm module loaded. lash was compiled with gcc 4.0.3 using the following configure flags:
--prefix=/usr --sysconfdir=/etc --localstatedir=/var
--mandir=/usr/share/man --infodir=/usr/share/info
--enable-debug --enable-gtk2 --build=i686-pc-linux-gnu

CFLAGS used are:
-march=pentium-m -mmmx -mfpmath=sse -msse2 -pipe -Os

Attached is the output from valgrind.
