Building gdb with --enable-build-with-cxx=no trips on a warning: ../../binutils-gdb/gdb/rust-lang.c:173:15: error: saveptr may be used uninitialized in this function [-Werror=maybe-uninitialized] ret.name = concat (TYPE_NAME (type), "::", token, (char *) NULL); The problem is that gcc doesn't understand that "tail" can never be NULL in the call to strtok_r: name = xstrdup (TYPE_FIELD_NAME (type, 0)); cleanup = make_cleanup (xfree, name); tail = name + strlen (RUST_ENUM_PREFIX); ... for (token = strtok_r (tail, "$", &saveptr); Fix this by always initializing saveptr. 2016-06-29 Manish Goregaokar <manish@mozilla.com> gdb/ChangeLog: * rust-lang.c (rust_get_disr_info): Initialize saveptr to NULL.
