This variable is used once in an assertion. Remove single declaration and access directly in the assert(). See in "qemu/osdep.h": * [...] disable assertion is not * supported upstream so the risk is all yours. Meanwhile, please * submit patches to remove any side-effects inside an assertion, or * fixing error handling that should use Error instead of assert.
