18931c8927
The expression to compute the padding needed to fill the uc_sigmask field to 1024 bits actually computes the padding needed for 1080 bits. Fortunately, due to the 16-byte alignment of the following field (uc_mcontext) the definition in glibc contains enough bytes of padding after uc_sigmask so that the overall offsets and size match in both definitions.
