Looks like this issue only happens when iostream is included since iostream has a static global variable that causes issues. https://github.com/gcc-mirror/gcc/blob/07f497c2da3600cc99cd7d1b5c6726972fb2b5a1/libstdc%2B%2B-v3/include/std/iostream#L78 https://github.com/gcc-mirror/gcc/blob/ec59848074ba8c4310cbadb603822bfaeff03a32/libstdc%2B%2B-v3/src/c%2B%2B98/ios_base_init.h #if __has_attribute(init_priority) static ios_base::Init __ioinit __attribute__((init_priority(90))); #endif It has this new init_priority attribute.
