Bug report

I'm compiling python as a static library to embed in my c++ shared library, and-fPIC is necessary to get it working!

compilation command:CFLAGS=-fPIC ./configure --enable-shared=no --enable-optimizations

the following error happens:

Objects/typeobject.c: In function ‘inherit_special’:Objects/typeobject.c:5777:1: error: the control flow of function ‘inherit_special’ does not match its profile data (counter ‘arcs’) [-Werror=coverage-mismatch] 5777 | inherit_special(PyTypeObject *type, PyTypeObject *base)      | ^~~~~~~~~~~~~~~Objects/typeobject.c:5777:1: error: the control flow of function ‘inherit_special’ does not match its profile data (counter ‘time_profiler’) [-Werror=coverage-mismatch]Objects/typeobject.c: In function ‘object_set_class’:Objects/typeobject.c:4774:1: error: the control flow of function ‘object_set_class’ does not match its profile data (counter ‘arcs’) [-Werror=coverage-mismatch] 4774 | object_set_class(PyObject *self, PyObject *value, void *closure)      | ^~~~~~~~~~~~~~~~Objects/typeobject.c:4774:1: error: the control flow of function ‘object_set_class’ does not match its profile data (counter ‘time_profiler’) [-Werror=coverage-mismatch]Objects/obmalloc.c:1449:1: warning: ‘always_inline’ function might not be inlinable [-Wattributes] 1449 | arena_map_get(block *p, int create)      | ^~~~~~~~~~~~~

if I remove the-fPIC it compiles fine!
edit: Just tried removing--enable-optimizations and it worked, but I think it should work with optimizations?
