ICE caused by using feature(generic_const_exprs)

[iamanonymouscs]

Code

The code runs as expected until we introduce the generic_const_exprs attribute and the compiler encounters an ICE error.

Based on the description provided in the document, if two Internal Compiler Errors (ICEs) have different query stacks, they are considered as separate bugs. Therefore, it is believed that ICE #114463 is distinct from ICE #114212.
