Issue 28119: Explicit null dereferenced in formatter_unicode.c (original) (raw)

Coverity is warning about four cases of potential NULL forwarding in which subsequent code does not expect a NULL value.

1. no_write_call: Although get_locale_info does overwrite locale.decimal_point on some paths, it also contains at least one feasible path which does not overwrite it.
