This issue might be a duplicate of existing issues. Please check:
Mouse Input Spam / SIGPWR Signal Storm in WSL2 #5168: Similar SIGPWR signal storm issue — that report covers the same symptom (process receiving continuous SIGPWR signals) on NixOS/WSL2. The root cause may be the same even though your environment is native Gentoo Linux rather than WSL2.
If you can run strace opencode and share the output, it would help confirm whether the same signal-flooding pattern is occurring.

how could this be duplicated with #27419
IMO, they are not related. I have glibc 2.42 installed, and it still crashes...
simonklee commentedon May 14, 2026
You're right, thanks!
yangyingchao commentedon May 14, 2026
Weird...
I tried this version under tty (not in a terminal simulator like Foot), and it works...
And I tried
strace -e signal,write opencodeof version 1.14.48, there are lots of SIGTERM too...yangyingchao commentedon May 14, 2026
Just tested again, 1.14.49 works under pure TTY & kitty...

I think this might be an issue of foot terminal.
Raised an issue for foot: https://codeberg.org/dnkl/foot/issues/2335.

Thanks. I looked into this today and simply sending OSC 99 in foot crashes it.

Thank you for the quick reaction and fix @simonklee 👍
simonklee commentedon May 15, 2026
We'll try to get a workaround out in next release.
Naasha commentedon May 16, 2026
Hello, I just installed foot 1.27.0 and I can confirm that opencode 1.15.0 is starting properly.
simonklee commentedon May 16, 2026
A workaround was released in OpenCode v1.15.1 that works with older foot terminals as well.
