When reading the .map file for JIT usage in perf report using
the TUI interface there is a specific circumstance where perf
closes almost immediately.
A quick refresher on the contents of the .map file:
<address> <instruction size> <instruction>
The bug is manifested when the same address is listed twice, but
the instruction size differs.
This bug does not occur with the stdio or gtk interfaces.
I plan on attempting to fix this issue. Though my coding chops
aren't yet at par with kernel development. Hence why I post this
now in the case someone else wishes to investigate and is able
to create a patch first.
Please CC me on any response.

I see on LKML:

I assume that means my email isn't available for CC'ing. So now
I feel the fool.
