gcc 10.2.0 complains getcwd() could return address of local variable

[axel-h]

With gcc 10.2.0 I get this warning for getcwd()

.../libs/musllibc/src/unistd/getcwd.c: In function 'getcwd':
cc1: warning: function may return address of local variable [-Wreturn-local-addr]
...libs/musllibc/src/unistd/getcwd.c:9:7: note: declared here
    9 |  char tmp[PATH_MAX];
      |    

To be checked if this has been fixed in upstream musllibc already.
