Bug ID: 55460
           Summary: itss:protocol - test_its_protocol_info() sometimes
                    fails on w7u
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2

itss:protocol - test_its_protocol_info() sometimes fails on w7u:

protocol.c:484: Test failed: [11] unexpected size=31
protocol.c:487: Test failed: [11] unexpected result:
L":test.chm::blank.htmltest.html"

See https://test.winehq.org/data/patterns.html#itss:protocol

The failures first happened on 2023-07-13 and have happened about once a week
since.
They also seem to be specific to the w7u VM, in particular they did not happen
on w7pro64 yet.

--- Comment #1 from François Gouget  ---
I could not bisect this set of failures because:
* I got failures even with the 2023-06-01 source (0336d66ea192). So this issue
existed way before the first instance in a regular WineTest run.
* This does not match any of the recent environment changes: it predates GitLab
CI's switch to Debian 12 builds (2023-07-10), there has been no change in the
w7u test configurations (the live snapshots are dated 2022-06-06).

--- Comment #2 from François Gouget  ---
I have now tested with an itss_test.exe binary built on Debian 11 and was not
able to reproduce this failure even after 377 runs. Meanwhile using Debian 12
builds the failure pretty reliably happen in under 25 runs.

Given the low failure rate the timing of the first nightly failure is
consistent with the GitLab CI switch to Debian 12.
