reportbug was patched to copy -lts and -security bugs to the appropriate addresses.

Note that jessie has GCC 4.9, so this probably needs to use the explicit version: static inline gboolean _GLIB_CHECKED_MUL_U32 (guint32 *dest, guint32 a, guint32 b) { *dest = a * b; return !a || *dest / a == b; } #define g_uint_checked_mul(dest, a, b) \ _GLIB_CHECKED_MUL_U32(dest, a, b) Cheers, Emilio
