perf 6.9-1 (archlinux) crashes during recording of cycles + raw_syscalls

[Milian Wolff <milian.wolff@kdab.com>]

Hey all,

the following command crashes perf for me, is this still an issue upstream and 
should I report it to arch for backporting? I cannot build the official perf/
core branch, so I am afraid I cannot test it myself there:

```
sudo /usr/bin/perf record -z --call-graph dwarf -e cycles -e 
raw_syscalls:sys_enter ls
...
[ perf record: Woken up 3 times to write data ]
malloc(): invalid next size (unsorted)
Aborted
```

Backtrace with GDB + debuginfod:
```
malloc(): invalid next size (unsorted)

Thread 1 "perf" received signal SIGABRT, Aborted.
