Hi,

dumpasn1 currently fails to build from source on armhf. The failure is due to
an incompatibility between valgrind and stack-clash-protection on 32bit arm
reported upstream at: https://bugs.kde.org/show_bug.cgi?id=479699

While waiting for valgrind to get updated, please cosider addressing the
immediate issue by disabling stack-clash-protection on armhf with the following
snippet in d/rules:

  ifeq ($(DEB_TARGET_ARCH),armhf)
    export DEB_BUILD_MAINT_OPTIONS = hardening=+all,-stackclash
  else
    export DEB_BUILD_MAINT_OPTIONS = hardening=+all
  endif

The build error looks like this:

     1052468                       | base64 -d
     1052469 Segmentation fault      | valgrind --error-exitcode=17 -- "$DUMPASN1" -
make[1]: *** [debian/rules:24: override_dh_auto_test] Error 139

Thanks,
