Bug ID: 15534
Summary: ld breaks malloc when -fPIE -pie is used on solaris
sparcs
Product: binutils
Version: 2.23
Status: NEW
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: jullien at eligis dot com
using pie on solaris 10 sparc breaks malloc (malloc returns 0 NOMEM):
Using gcc 4.8 and all recent gnu tools compiled with:
../configure \
--with-gnu-as --with-as=/usr/local/bin/as \
--with-gnu-ld --with-ld=/usr/local/bin/ld \
--enable-shared \
--disable-nls \
--enable-languages=c,c++
on good old UltraSparc 10 having 512Mb of mem gives me a malloc error using
this simple test:
#include <stdlib.h>
#include <stdio.h>
int
main()
{
printf("malloc %p\n", malloc(100));
}
$ gcc -o foo -fPIE -pie foo.c && ./foo
malloc 0
$ gcc -o foo foo.c && ./foo
malloc 20918
Standard solaris ld, silently ignores pie request and program works well.
Two acceptable solutions I see:
- raise an error, "ld does not support pie on this architecture"
- silently ignore pie as does solaris sparc ld

Thank you for your attention
