[Pkg-pascal-devel] Bug#1016556: fpc: glibc 2.34 breaks fpc autopkgtest on arm64: undefined reference to `__libc_csu_init'

Dear maintainer,

The autopkgtest of fpc fails in sid on amd64 when that autopkgtest is
run with the binary packages of glibc from experimental. It passes when
run with only packages from sid. In tabular form:

                     pass            fail
glibc                from sid        2.34-0experimental5
fpc                  from sid        3.2.2+dfsg-10
all others           from sid        from sid

Here is the relevant part of the test log:

The full test log is available there:

It seems that the startup code has to be adjusted for glibc 2.34, Ubuntu
has a patch available there:
