Description Richard W.M. Jones 2014-07-15 18:14:14 UTC
Description of problem:

$ touch test.c
$ gcc -S test.c
$ cat test.s

On != aarch64, gcc emits a GNU_STACK directive:

	.section	.note.GNU-stack,"",@progbits

On aarch64, this is missing, so all of our binaries probably
run with an executable stack.

Version-Release number of selected component (if applicable):

gcc-4.9.0-14.fc21.aarch64

How reproducible:

100%

Steps to Reproduce:
1. See above.

Comment 1 Richard W.M. Jones 2014-07-15 18:18:50 UTC
Looks as if we need this patch:

Comment 3 Jakub Jelinek 2014-09-29 16:12:44 UTC
Should be fixed in more contemporary rawhide/f21 gcc builds.
