step:

  1. cmake-gui configure
  2. open SDL2.sln
  3. build testyuv release

Perhaps duplicate of #3662 , you can enable LIBC option as workaround. (For both GCC and MSVC,) there's no straightforward way to disable specific optimization that can insert memset etc.

IMHO, static library build should not include its own memset and should defer these to linked executables.

the error only occur on build release ,debug build can work well

Results can be inconsistent between optimization levels because static-linking do not guarantee pulling entire .objs in the library and optimization might add/remove function calls.

Re.this particular case, difference comes from MSVCRT(D).LIB.

Only release version of the runtime library uses memset function and it ultimately pulls that symbol.
