--- Comment #3 from suratiamol at gmail dot com ---
Got the same error here too.
The error, at least in the case of __asprintf, seems to occur because there are
two declarations:
// emitted by libio/bits/stdio-ldbl.h
// __LDBL_REDIR2_DECL (asprintf)
// commit: e4a399921390509418826e8e8995d2441f29e243
extern __typeof (__asprintf) __asprintf __asm ("" "__nldbl___" "asprintf");
// emitted by include/stdio.h
// libc_hidden_ldbl_proto (__asprintf)
// commit: 45ae17dd7ed3b9dea0d698d1c37a978d8d0a9aa2
extern __typeof (__asprintf) __asprintf __asm__ ("" "__GI___asprintf")
__attribute__ ((visibility ("hidden")));
It is likely that the same two commits are involved in the errors about other
symbols.
Can reproduce the error with this dummy sample:
extern int __asprintf(void);
extern __typeof(__asprintf) __asprintf __asm("__nldbl___" "asprintf");
extern __typeof(__asprintf) __asprintf __asm__("__GI___asprintf")
__attribute__((visibility("hidden")));
int main(){return 0;}
//cc a.c -Werror
