After discussing the issue on the OpenBSD matrix channel
jrick explained me that the issues comes from the init
part of libc here:
https://gitlab.com/cznic/libc/-/blob/v1.38.0/libc_openbsd.go#L49

He showed me the error could be reproduced with this simple
program:

--
package main

import _ "modernc.org/libc"

func main() {}
--

Running this program gives:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x4caebc]

goroutine 1 [running]:
modernc.org/libc.(*TLS).setErrno(0x5d2940?, {0x4d77c0?, 0x520938?})
	/home/hukadan/go/pkg/mod/modernc.org/libc@v1.38.0/etc.go:190 +0xdc
modernc.org/libc.Xmalloc(0xc00011fe00?, 0x521630?)
	/home/hukadan/go/pkg/mod/modernc.org/libc@v1.38.0/mem.go:37 +0xc5
modernc.org/libc.init()
	/home/hukadan/go/pkg/mod/modernc.org/libc@v1.38.0/libc_openbsd.go:49 +0x23b


And the corresponding kdump: http://pastebitch.com/SPLJ

I will try to file a bug report on modernc in the coming days.
