re PR middle-end/50141 (ICE: tree check: expected var_decl, have parm_decl in get_bit_range, at expr.c:4357 with --param allow-store-data-races=0 and bitfields)
PR middle-end/50141
* expr.c (get_bit_range): Only use DECL_THREAD_LOCAL_P if
innerdecl is a VAR_DECL.
* c-c++-common/cxxbitfields-6.c: New test.
