            Bug ID: 17560
           Summary: mips: assertion failure with --as-needed + weak +
                    hidden main function
           Product: binutils
           Version: 2.26 (HEAD)
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ld
          Assignee: unassigned at sourceware dot org
          Reporter: james410 at cowgill dot org.uk

With the combination of:
- MIPS
- Linking with --as-needed
- The main() function being declared hidden
- Linking with a shared library which references main() declared as weak

Causes this error:
>/home/jcowgill/binutils-gdb/ld/.libs/lt-ld-new: BFD (GNU Binutils)

test-obj.c
====
__attribute__((visibility ("hidden"))) int main(void)
{
        return 42;
}

test-dso.c
====
__attribute__((weak)) int main(void);

int blob(void)
{
        return main();
}

compile with
====
gcc -c test-obj.c
gcc -shared -fPIC -o test-dso.so test-dso.c
gcc -Wl,--as-needed test-obj.o test-dso.so
