--- Comment #4 from H.J. Lu <hjl.tools at gmail dot com> ---
Overflow check doesn't work x32:

address@hidden pr18695]$ cat x.S
        .hidden foo
        .comm pad,0x8ff00000,8
        .comm foo,8,8
        .text
        .globl  bar
        .type   bar, @function
bar:
        lea     foo(%rip), %rax
address@hidden pr18695]$ make x32.so
gcc -mx32 -g -c -o x32.o x.S
./ld.gold -m elf32_x86_64 -z max-page-size=0x200000 -shared -o x32.so x32.o
address@hidden pr18695]$ ld.bfd  -m elf32_x86_64 -z max-page-size=0x200000 
-shared
-o x32.so x32.o
x32.o: In function `bar':
/export/home/hjl/bugs/binutils/pr18695/x.S:8:(.text+0x3): relocation truncated
to fit: R_X86_64_PC32 against symbol `foo' defined in COMMON section in x32.o
