I should have tested with different compilers before posting the
previous comment since Eli predicted that a bad compiler is a problem.
Yes, the results differ depending on the compiler you use.
Here is the results:
- All test is done with 7bf54d0 + the previous patch applied
- no option to configure except specifying compiler with CC=
| gcc 6 | good | 6.1.1 20160705 (Debian 6.1.1-9) |
| gcc 5 | bad | 5.4.0 20160609 (Debian 5.4.0-6) |
| gcc 4.9 | good | 4.9.3 (Debian 4.9.3-14) |
| gcc 4.8 | good | 4.8.5 (Debian 4.8.5-4) |
- good: returns 10
- bad: returns 20
So the current default compiler on Debian Sid is the one to create a
bad binary with the current source code.
Let me know if you need any other info.
