So, due to the complexity of dealing with different gcc versions and the
limitations of uprobes, the test/unittest/pid/tst.emptystack.d fails on
Debian unstable because the kernel is unable to place a uprobe on one of
the instructions.
The test fails because the stderr output reports:
dtrace: Failed to enable uprobe:ca21_17c733:main:1062
Disassembly of section .text:
0000000000001050 <main>:

1058: f2 0f 2a d7 cvtsi2sd %edi,%xmm2
105c: f2 0f 11 54 24 08 movsd %xmm2,0x8(%rsp)
==> 1062: 66 66 2e 0f 1f 84 00 data16 cs nopw 0x0(%rax,%rax,1)
1069: 00 00 00 00
106d: 0f 1f 00 nopl (%rax)
I am not sure how to best handle this discrepancy.
