Hi all,I’m seeing this warning with more modern Apple compilers for lyx-2.3.x: lyx-2.3.x/src/graphics/PreviewLoader.cpp:730:28: warning: result of '2^20' is 22; did you mean '1 << 20' (1048576)? [-Wxor-used-as-pow] static atomic_int fake((2^20) + 1); ~^~~ 1 << 20 lyx-2.3.x/src/graphics/PreviewLoader.cpp:730:28: note: replace expression with '0x2 ^ 20' or use 'xor' instead of '^' to silence this warning This was fixed in master. Shouldn’t the fix be backport to 2.3.x?
I suppose, but I'm confused. Why is 2^20 = 22? Overflow? Or does ^ not mean what I thought it did?
