Describe the bug
SIGSEGV instead of clean exit.

To Reproduce
Start hotspot (in my case from appimage) with a perf file, then close the window during read.

Expected behavior
Clean exit

Version Info (please complete the following information):

  • Linux Kernel version: 4.18.0-513.9.1.el8_9.x86_64
  • perf version: perf version 4.18.0-513.18.1.el8_9.x86_64
  • hotspot version (appimage? selfcompiled?): appimage from 1.5.1 release
