Hi, This issue was fixed in:
https://salsa.debian.org/lintian/lintian/commit/9d580d4401f7501a3b1634dfe69b116901826491
The problem was caused by unsuccessful network access in the backend
XML::LibXML::SAX::Parser. The problematic packages contained XML files
that somehow did not parse correctly. The call to the parser never
returned. The issue occurred even when XML::LibXML was used directly
(without XML::Simple), but without the option 'no_network'.
For future reference, a test script and the two problematic XML files
are attached.
The issue may have been caused by a breaking change in
libxml-libxml-perl, but I am not sure.
Kind regards
Felix Lechner

<!-- ================================ DESCRIPTION -->
<refsect1 id="description"><title>Description</title>
<para>
The <function>#pragma OPENCL EXTENSION</function> directive is a simple, low-level
mechanism to set the behavior for each extension. It does not define policies such
as which combinations are appropriate; those must be defined elsewhere. The order of
directives matter in setting the behavior for each extension. Directives that occur
later override those seen earlier. The <function>all</function> variant sets the
behavior for all extensions, overriding all previously issued extension directives,
but only if the <varname>behavior</varname> is set to <function>disable</function>.
</para>
<para>
The initial state of the compiler is as if the directive <function>#pragma OPENCL
EXTENSION all : disable</function> was issued, telling the compiler that all error and
warning reporting must be done according to this specification, ignoring any extensions.
</para>
<para>
Every extension which affects the OpenCL language semantics, syntax or adds built-in
functions to the language must create a preprocessor <code>#define</code> that
matches the extension name string. This <code>#define</code> would be available in
the language if and only if the extension is supported on a given implementation.
</para>
</refsect1>
<!-- ================================ NOTES -->
<refsect1 id="notes"><title>Notes</title>
<para>
This document describes the list of optional features supported by OpenCL 1.2.
Optional extensions may be supported by some OpenCL devices. Optional extensions are
not required to be supported by a conformant OpenCL implementation, but are expected
to be widely available; they define functionality that is likely to move into the
required feature set in a future revision of the OpenCL specification
</para>
<para>
OpenCL extensions approved by the OpenCL working group can be promoted to required core
features in later revisions of OpenCL. When this occurs, the extension specifications
are merged into the core specification. Functions and enumerants that are part of
such promoted extensions will have the KHR affix removed. OpenCL implementations of
such later revisions must also export the name strings of promoted extensions in the
<constant>CL_PLATFORM_EXTENSIONS</constant> or <constant>CL_DEVICE_EXTENSIONS</constant>
string, and support the KHR-affixed versions of functions and enumerants as a
transition aid.

<!-- ================================ EXAMPLE -->

Example
</title>
<para>
An extension which adds the extension string "cl_khr_3d_image_writes" should also add a
preprocessor <code>#define</code> called <constant>cl_khr_3d_image_writes</constant>. A
kernel can now use this preprocessor <code>#define</code> to do something like the
following:
