#119614 led to validation of promoteds recursing into statics. These statics can point to static mut and interior mutable static and do other things we don't allow in const, but promoteds are validated as const, so we get strange errors (saying "in const" when there is no const) and surprising validation failures.

#120960 fixes that; this here adds another test.

add another test for promoteds-in-static

rust-lang#119614 led to validation of promoteds recursing into statics. These statics can point to `static mut` and interior mutable `static` and do other things we don't allow in `const`, but promoteds are validated as `const`, so we get strange errors (saying "in `const`" when there is no const) and surprising validation failures.

rust-lang#120960 fixes that; this here adds another test.
