ghostscript breaks asymptote autopkgtest: build fails: GPL Ghostscript 9.55.0: Unrecoverable error, exit code 1

[Graham Inggs]

Since the upload of ghostscript/9.55.0~dfsg1-0ubuntu1, asymptote's autopkgtests are failing on armhf. (They've always failed on !armhf in Ubuntu, possibly due to LTO).

From https://bugs.debian.org/1000781

Dear maintainer(s),

With a recent upload of ghostscript the autopkgtest of asymptote fails
in testing when that autopkgtest is run with the binary packages of
ghostscript from unstable. It passes when run with only packages from
testing. In tabular form:

                       pass fail
ghostscript from testing 9.55.0~dfsg-1
asymptote from testing 2.70+ds-2
all others from testing from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration of ghostscript to
testing [1]. Due to the nature of this issue, I filed this bug report
against both packages. Can you please investigate the situation and
reassign the bug to the right package?
