Hm, this regresses for some symbols, the annotation window only
shows this:

__strlen_sse2_pminub
â
â

It used to show the full thing:

__strlen_sse2_pminub
0.00 : 392a35dbde: jne 392a35dc30
<__strlen_sse2_pminub+0x2a0> â
0.00 : 392a35dbe0: pcmpeqb 0x40(%rax),%xmm3
â
0.00 : 392a35dbe5: pmovmskb %xmm3,%edx
â
0.00 : 392a35dbe9: sub %rdi,%rax
â
0.00 : 392a35dbec: bsf %rdx,%rdx
â
0.00 : 392a35dbf0: add %rdx,%rax
â
0.00 : 392a35dbf3: add $0x40,%rax
â
0.00 : 392a35dbf7: retq

Other symbols are fine.
