Thanks for the logs. The offending call is: ``` 1 pidfd_open(1,0) = 9 1 pidfd_send_signal(9,0,NULL,0) = 0 1 clone(CLONE_VM|CLONE_VFORK|0x1011,child_stack=0x0000000000000000,parent_tidptr=0x00000040002872b8,tls=0x0000000000000000,child_tidptr=0x0000000000000000) = -1 errno=22 (Invalid argument) ``` Flag `0x1000` is `CLONE_PIDFD`.

cmd/compile: Increasing complexity when inlining

runtime: green tea garbage collector

Oops, that looks like a bug in cmd/go (in your installed version, not 1.25rc1) where it crashes if there is a GOEXPERIMENT the installed version doesn't know about before it...
