Subject: [C++ Patch] PR 51313

Hi,

here we ICE in C++11 mode in null_ptr_cst_p because integer_zerop is true for a NOP_EXPR, which TREE_OVERFLOW cannot handle. Thus the idea is using STRIP_NOPS in C++11 mode too: makes sense to me unless we have reasons of principle to exclude NOPs in that mode. Anyway, patch passes testing on x86_64-linux.

Thanks,
Paolo.
