After the prior fixes for PR121411, this could cause the struct size to be truncated when encoding extremely large structs on a host where size_t is smaller than unsigned HOST_WIDE_INT, manifesting for example as the test failure reported in PR121903. Change the argument to uHWI to resolve the issue. PR debug/121411 PR debug/121903 gcc/ * ctfc.h (ctf_add_sou): Change size arg from size_t to uHWI. * ctfc.cc (ctf_add_sou): Likewise.
