[sudo-users] [BUG] Another system (solaris 10 sparc) requires --disable-pie flag

Sat May 25 00:15:34 MDT 2013

Hi Todd,

It appears now this is a gcc/binutils bug. I filled
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=57409
Thank you for your time and the great job you make on sudo.

I'll now compile sudo without -pie and all is Ok.

Christian

Here's what I get:

$ gcc -o foo foo.c
$ ./foo
malloc 20d18
$ gcc -o foo -pie foo.c
$ ./foo
malloc 20d18
$ gcc -o foo -pie -fPIE foo.c
$ ./foo
malloc 20d30
$ gcc -o foo -pie -fpie foo.c
$ ./foo
malloc 20d28

I suspect there is something wrong with your gcc toolchain.  Is your gcc
built to use the Solaris or GNU linker?  Here's the verbose output I see.

$ gcc -o foo -v -fPIE -pie foo.c
