With recent changes to Google Search JavaScript, searching terminates Browse with a SIGSEGV, in WTF::dtoa.
http://bugs.sugarlabs.org/ticket/4785 This is only seen on an XO-1, in 13.2.1, 13.2.0, all the way back to 12.1.0. It is not seen on more recent XO laptops. On Fedora 20, with Sugar 0.102, and Browse-156, on kernel 3.10, does similar, but the failure is SIGILL. Using gdb we find the failing instructions are references to XMM registers: 0xabeda509: mov 0x4(%eax),%ebx 0xabeda50c: cmp -0x8(%ebx),%ecx 0xabeda50f: jae 0xabedbcde => 0xabeda515: movsd (%ebx,%ecx,8),%xmm0 <= 0xabeda51a: ucomisd %xmm0,%xmm0 0xabeda51e: jp 0xabedbcde 0xabeda524: movd %xmm0,%eax The XO-1 with AMD Geode processor does not have these registers, so the SIGILL is valid. So it would seem one way to fix this may be to rebuild WebKit without this instruction stream. But first, I want to make sure I can rebuild WebKit. I've tried on a Fedora 20 system to do this: yumdownloader --source webkitgtk3 rpmrebuild --rebuild webkitgtk3-1.10.2-3.fc18.src.rpm But it fails with this: libtool: link: gcc -o /root/rpmbuild/BUILD/webkitgtk-1.10.2/tmp-introspectHnbXap/.libs/WebKit-3.0 -O2 -g1 -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m32 -march=i686 -mtune=atom -fasynchronous-unwind-tables -DLIBSOUP_I_HAVE_READ_BUG_594377_AND_KNOW_SOUP_PASSWORD_MANAGER_MIGHT_GO_AWAY -O2 -Wl,-z -Wl,relro /root/rpmbuild/BUILD/webkitgtk-1.10.2/tmp-introspectHnbXap/WebKit-3.0.o -Wl,--export-dynamic -pthread -Wl,--export-dynamic -L. /root/rpmbuild/BUILD/webkitgtk-1.10.2/.libs/libwebkitgtk-3.0.so /root/rpmbuild/BUILD/webkitgtk-1.10.2/.libs/libjavascriptcoregtk-3.0.so -lgmodule-2.0 -lrt -lgtk-3 -lgdk-3 -latk-1.0 -lpangocairo-1.0 -lgdk_pixbuf-2.0 -lcairo-gobject -lpango-1.0 -lcairo -lsoup-2.4 -lgio-2.0 -lgobject-2.0 -lglib-2.0 -pthread /lib/libGL.so.1: undefined reference to `_glapi_tls_Dispatch' /lib/libEGL.so.1: undefined reference to `wl_display_dispatch_queue_pending' collect2: error: ld returned 1 exit status linking of temporary binary failed: Command '['./doltlibtool', '--mode=link', '--tag=CC', 'gcc', '-o', '/root/rpmbuild/BUILD/webkitgtk-1.10.2/tmp-introspectHnbXap/WebKit-3.0', '-export-dynamic', '-O2', '-g1', '-pipe', '-Wall', '-Wp,-D_FORTIFY_SOURCE=2', '-fexceptions', '-fstack-protector', '--param=ssp-buffer-size=4', '-m32', '-march=i686', '-mtune=atom', '-fasynchronous-unwind-tables', '-DLIBSOUP_I_HAVE_READ_BUG_594377_AND_KNOW_SOUP_PASSWORD_MANAGER_MIGHT_GO_AWAY', '-O2', '-Wl,-z,relro', '/root/rpmbuild/BUILD/webkitgtk-1.10.2/tmp-introspectHnbXap/WebKit-3.0.o', '-L.', '-lwebkitgtk-3.0', '-ljavascriptcoregtk-3.0', '-Wl,--export-dynamic', '-pthread', '-lgmodule-2.0', '-lrt', '-lgtk-3', '-lgdk-3', '-latk-1.0', '-lpangocairo-1.0', '-lgdk_pixbuf-2.0', '-lcairo-gobject', '-lpango-1.0', '-lcairo', '-lsoup-2.4', '-lgio-2.0', '-lgobject-2.0', '-lglib-2.0']' returned non-zero exit status 1 make[1]: *** [WebKit-3.0.gir] Error 1 make[1]: Leaving directory `/root/rpmbuild/BUILD/webkitgtk-1.10.2' make: *** [all] Error 2 error: Bad exit status from /var/tmp/rpm-tmp.vGFtGZ (%build) -- James Cameron http://quozl.linux.org.au/ _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
