I'd bet it is a variant of this:

Hi yoto-devs/users,

in order to get a golang application to run which relies on `go
generate` calls I wrote special recipes for this tools and include them
in my original recipe. However I always get a segmentation fault.
In the tools (which happens to be based on golang too) I use [1] in the
recipes and in the recipe I want to use them I include them via [2].
However if for example enter the dev-shell or during build I get a
segmentation fault although the binary seems to be compiled for the
right architecture (host-amd64).
Is there something wrong I try to use that?
do you have stack trace ? that might give some more info on whats going on
