The same test case as in 51060
Related to:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=51060
The only difference between this issue and 51060 is that code is being compiled
without "Os".
$ g++ -c 51060.cpp -Wframe-larger-than=2048 -Werror
51060.cpp: In function ‘void Test()’:
51060.cpp:37:1: error: the frame size of 10240 bytes is larger than 2048 bytes
[-Werror=frame-larger-than=]
}

cc1plus: all warnings being treated as errors
See attached code sample.
