SDL2 SDL_Init function triggers memory sanitizer error (relying on uninitialized data)

Question

clang -g -fsanitize=memory -Wconversion -Wsign-conversion -Wextra -Wall -Werror -pedantic -I/usr/include/SDL2 -lSDL2_image -lSDL2_gfx -lSDL2 -lSDL2_ttf -lc -lm ./deps/**/*.c ./src/*.c ./src/**/*.c -o ./bin/output

./bin/output

Uninitialized bytes in __interceptor_strlen at offset 5 inside [0x717000000310, 6)

Logs show the last code I could have possibly written myself was at main:33:5, which is the first line of main() that just contains SDL_Init(SDL_INIT_EVERYTHING);

Does SDL do that intentionally, if so, is there a way to supress that?
