https://github.com/thephoeron/cl-isaac/issues/10 I put this here to make sbcl devs aware of this
6:23:24

is the part that sbcl devs would care about that restrict-compiler-policy isn't working on macos?
8:08:05
|3b|
it also mentions something about THE with high safety, but not /what/ and seems to think it is working as intended so not a bug?
8:09:26
|3b|
behavior of THE when the value isn't that type (as in the earlier comments) is undefined, so is expected to be non-portable across implementations
8:26:24

Josh_2: the pasted examples in the bug don't seem to show the code being recompiled in the macos case

Okay well unfortunately I dont actually know whats going on with cl-isaac itself, I am simply a messenger in this case. However I can say that I have used a build pipeline with gitlab to try and deploy software that was depending on cl-isaac that used restrict-compiler-policy and this problem has occurred when its set to safety 3

ACTION 's guess was something else changing the restriction, but failing to recompile seems much more likely (and fits the available evidence)
8:31:53
|3b|
ACTION couldn't find any information about what was wrong with THE, particularly in context of undefined behavior where nothing is 'wrong' at the CL level

(so SBCL and some other impl can do completely different things and still be 'correct' to their own interpretations, and users can't complain since their code is non conformant)
