Hi Arnaldo, Jiri

Running this simple command from tip.git tree, I get:


$ perf record ls

[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.011 MB perf.data (9 samples) ]

$ perf script
Segmentation fault (core dumped)

$ gdb perf
(gdb) r script

Program received signal SIGSEGV, Segmentation fault.

Looks like something is fundamentally broken here.
Do you know what?
