Hmm, yeah, you are right. But it doesn't work!
$ g++ test.cc -O2 -lssp_nonshared
C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/9.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe:
C:\msys64\tmp\ccmAuUCu.o:test.cc:(.text.startup+0x1f): undefined
reference to `__strcpy_chk'
collect2.exe: error: ld returned 1 exit status
$ nm /mingw64/lib/gcc/x86_64-w64-mingw32/9.2.0/libssp_nonshared.a
libssp_nonshared_la-ssp-local.o:
0000000000000000 b .bss
0000000000000000 d .data
0000000000000000 r .pdata
0000000000000000 r .rdata$zzz
0000000000000000 t .text
0000000000000000 r .xdata
U __stack_chk_fail
0000000000000000 T __stack_chk_fail_local
So I guess that's actually for something else? I think
https://sourceware.org/ml/gdb-patches/2019-12/msg00787.html is the
best option.
