------- Comment #2 from ccof...@novell.com 2007-07-06 13:34 ------- Strict aliasing (which defaults to on in gcc 4.2 when using -O2, -O3, or -Os) is breaking libxenstore. As posted on xen-devel, a work-around is:

--- xen-3.1-testing.orig/tools/xenstore/Makefile +++ xen-3.1-testing/tools/xenstore/Makefile @@ -6,7 +6,7 @@ MAJOR = 3.0 MINOR = 0

PROFILE=#-pg -BASECFLAGS=-Werror +BASECFLAGS=-Werror -fno-strict-aliasing # Make gcc generate dependencies. BASECFLAGS += -Wp,-MD,.$(@F).d PROG_DEP = .*.d
