For some reasons gcc doesn't generate the right assembly when -O1 is specified on the command line. Which version of gcc do you use(4.7.*?)? Which distribution are you using? Can you also call disas the crash and copy the output? Gcc 4.8 doesn't seem to be affected. FYI, I got this output from 4.7 with Linaro Ubuntu raring (gcc 4.7.3). [...]I saw the same thing on my system and ack'ed that this is compiler related. My compiler is 4.7.3. I was able to fix it with the following hack:Are you also using the Linaro compiler by any chance? I think so. Here is the GCC --version info: arm-linux-gnueabihf-gcc (Ubuntu/Linaro 4.7.3-1ubuntu1) 4.7.3 I've added warnings to http://wiki.xen.org/wiki/Xen_ARM_with_Virtualization_Extensions/CrossCompiling and http://wiki.xen.org/wiki/Xen_ARM_with_Virtualization_Extensions#Building_Xen_on_ARM _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
