Bug ID: 57409
Summary: PIE (-fPIE -pie) prevents any malloc on Solaris 10
sparc
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: jullien at eligis dot com
Trying to build recent sudo versions which now uses PIE I got core dumps or
does memory failures since gcc 4.7. It appears the culprit is PIE.
Using 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 the same error using
this simple test:
#include <stdlib.h>
#include <stdio.h>
int
main()
{
return printf("malloc %p\n", malloc(100));
}
$ gcc -o foo -fPIE -pie foo.c && ./foo
malloc 0
$ gcc -o foo foo.c && ./foo
malloc 20918
here is the result of -v on
$ gcc -o foo -v -fPIE -pie foo.c
Using built-in specs.

Is there is something wrong on the way I compile gcc on solaris sparc? Except
for PIE, gcc 4.8 compiled ROOTB many big GNU and non-GNU projects without
error.
Tia for the time you may spend on this report.
