BIR verification failed when installing serapuem(required by spinneret)

[2403772980ygy]

When using quicklisp to install spinneret, a build failure emerged. (log attached below)

Code at issue

(ql:quickload "spinneret")

Other steps to reproduce
If the problem cannot be reproduced from just a code sample, include other steps here.

1. Remove ~/quicklisp and ~/.cache/common-lisp/clasp*
2. run clasp --load quicklisp.lisp and install quicklisp.
3. evaluate `(ql:quickload "spinneret")

  Not really relevant, but is Gentoo, llvm&clang16.

A brief log(the log contains like a million of lines so I'm just posting the last lines):

;   BIR verification failed. The IR is in an inconsistent state.
;   This probably indicates a problem in the compiler; please report it.

Condition of type: COMPILE-FILE-ERROR
COMPILE-FILE-ERROR while compiling #<CL-SOURCE-FILE "serapeum" "level1" "sequences">
Available restarts:
(use :r1 to invoke restart 1, etc.)

It seems that some packages have been updated these days. But with other flavors I haven't got such a problem.
