It's not perfect, but it does mention the method the user forgot to define.

A smaller testcase:

It is caused by compressed debug section change:
http://sourceware.org/ml/binutils/2010-07/msg00030.html
When linker report error, read_and_uncompress_section
changed the size of .debug_str:

Consider this inline assembly compiled by GCC on x86-64 Linux with the small
code model:
#include
typedef uint32_t u32x4_t __attribute__ ((vector_size (16)));
void decode_and_jump(u32x4_t instructions) {
void *ptr;
asm("movd %[from], %[to]\n" : [to] "=r" (ptr) : [from] "x" (instructions));
On Linux/x86-64, I got
[...@gnu-6 tmp]$ cat p.c
#include
int
main ()
{
pthread_create(NULL, NULL, NULL, NULL);
return 0;
}
[...@gnu-6 tmp]$ gcc p.c -g
collect2: ld terminated with signal 11 [Segmentation fault]
/tmp/cchrlmId.o: In function `main':
/tmp/p.c:6: undefined reference to `pthread_cr
In this testcase, .got.plt section isn't needed:
[...@gnu-6 gotplt-1]$ cat foo.c
static int bar ()
{
return 0x1234;
}
void *
foo ()
{
return &bar;
}
[...@gnu-6 gotplt-1]$ cat main.c
extern void * foo ();
extern void abort ();
int
main ()
{
int (*bar) () = foo ();
if (bar () != 0x1234)
