1 function with some indirect sub-type change:
[C] 'method virtual std::__codecvt_abstract_base<char16_t, char8_t,
__mbstate_t>::result std::codecvt<char16_t, char8_t,
__mbstate_t>::do_unshift(std::codecvt<char16_t, char8_t,
__mbstate_t>::state_type&, std::codecvt<char16_t, char8_t,
__mbstate_t>::extern_type*, std::codecvt<char16_t, char8_t,
__mbstate_t>::extern_type*, std::codecvt<char16_t, char8_t,
__mbstate_t>::extern_type*&) const' at codecvt.cc:914:1 has some indirect
sub-type changes:
Please note that the symbol of this function is
_ZNKSt7codecvtIDsDu11__mbstate_tE10do_unshiftERS0_PDuS3_RS3_@@GLIBCXX_3.4.26
and it aliases symbol:
_ZNKSt7codecvtIDiDu11__mbstate_tE10do_unshiftERS0_PDuS3_RS3_@@GLIBCXX_3.4.26
return type changed:
entity changed from 'typedef std::__codecvt_abstract_base<char16_t,
char8_t, __mbstate_t>::result' to compatible type 'enum
std::codecvt_base::result' at codecvt.h:52:1
