Bug ID: 58990
Summary: G++ generates duplicate labels for linux 32-bit when
optimization+LFS is enabled
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: novulae at hotmail dot com
GCC 4.4.5 compiles this code without issue, GCC 4.6.0 produces the below error,
as does GCC 4.8.0. This happens on linux 32-bit, but not 64-bit. I haven't
tried to see if g++ -m32 has the same issue when on linux 64-bit.
$ cat test.cpp
#include <sys/stat.h>
#include <stdint.h>
void *foo(bool var) {
if (var) return (void*)(intptr_t)&stat;
return (void*)(intptr_t)&stat64;
}
$ g++ -O1 -D_FILE_OFFSET_BITS=64 -c test.cpp
/tmp/ccI8JqrP.s: Assembler messages:
/tmp/ccI8JqrP.s:22: Error: symbol `stat64' is already defined
