Bug#1091023: cmake breaks lfortran autopkgtest

[Paul Gevers]

Source: cmake, lfortran
Control: found -1 cmake/3.31.2-1
Control: found -1 lfortran/0.42.0-1
Severity: serious

Dear maintainer(s),

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

                        pass            fail
cmake                  from testing    3.31.2-1
lfortran               from testing    0.42.0-1
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 cmake 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?
