I see. But I think it is better to apply at least this "debugging
purposes" attribute than nothing. It is only for older gcc versions.
And with __SSP__ checks it can be targeted just for
-fstack-protector-string CRT builds, which is what the original commit

Right... I forgot that UCRT's mbstate_t is a structure when was writing the

If I understand correctly the code at 3d-4c is the stack protection
check, which should have been disabled for that function. But because
the ___stack_chk_guard is being change

Ok. Thanks for info. And what in the case if mingw-w64 is compiled with
gcc-8 together with -fstack-protector in CFLAGS?
It may be a default option of an environment.
For example in MSYS2 when building a native package with `makepkg-mingw` the default flags ar

The attribute __no_stack_protector__ was introduced in the commit
a0e69f7bc83a ("crt/ssp: fix stack smashing protection bootstrapping").
Could you look at this issue? It looks like that gcc ignores this
attribute and hence the commit for this gcc build does noth
Hello,
When I'm trying to compile mingw-w64 with gcc 8.3 with enabled all
warnings, I'm getting following compile warning:
i686-w64-mingw32-gcc -DHAVE_CONFIG_H -I. -m32 -masm=att -I./include
"-I/usr/local/include" -I/mingw-w64/mingw-w64-headers/crt/
-I/mingw-w64/mingw-w64-headers/include/ -pip
All these functions have same declarations in #ifdef _UCRT and #else
blocks. The only difference is that in non-UCRT block functions vfwscanf,
vswscanf and vwscanf are declared without __cdecl. As all those functions
are with __cdecl calling convenion, they should be declared with __cdecl.
