Fatal error: fault on MacOS 13 Ventura

[hironichu]

Nuclei version: 2.7.2

Current Behavior:

Nuclei is crashing on start when running with latest version
the error seems to be "random" can be a Bus error or a SIGSEGV
updating to latest stable/beta of Go doesn't change much.

EDIT: I must also say, the previous version was working perfectly fine. (2.7.1)

Expected Behavior:

Nuclei should just show the help section.

Steps To Reproduce:

1. Get macos 13 ventura beta 1,
2. install latest Nuclei version
3. run and see the crash.

Anything else:

This was taken before updating to Go 1.19 beta 1

This crash is different and occured after installing Go 1.19 beta 1

After updating to Beta 2 and latest dev version of nuclei i get this different error..

I must also add that while installing Nuclei, i get this message :

ld: warning: non-standard -pagezero_size is deprecated when targeting macOS 13.0 or later
ld: warning: disabling chained fixups because of unaligned pointers in '_go.func.*'```

@hironichu thanks for sharing these details, while we continue to investigate this, just wanted to let you know that nuclei is built based on Go 1.18 so we do not suggest using Go 1.19 to build the nuclei, instead either you can download the compiled binary or rollback to Go 1.18 to build from source.

I couldn't reproduce this with the latest beta of go 1.19. I think random crashes can't be excluded with candidate releases. I suggest sticking to go1.18 for the time being until a stable version of go1.19 gets released.

[hironichu]

:,) but I wasn't using Go 1.19 it doesn't work in any version of Go on latest macos beta..

I tried because I wanted to know if it was related or not!
