Subject: Crash when running perf top with perf-6.17.7
Date: Wed, 5 Nov 2025 17:27:23 +0100 [thread overview]
Message-ID: <aQt66zhfxSA80xwt@gentoo.org> (raw)
Hi Arnaldo,
After updating to perf-6.17.7, perf top crashes for me (seems to happen
since perf-6.17, but doesn't happen with perf-6.16):
gentoo perf $ perf top
perf: Segmentation fault
-------- backtrace --------
perf: Segmentation fault
-------- backtrace --------
Segmentation fault (core dumped) perf top
The stack trace from the crash is below. If this is not enough information,
please let me know what additional information you'd like to have.
Best regards,
-Guilherme
Core was generated by `perf top'.
Program terminated with signal SIGSEGV, Segmentation fault.
