QSR Coin log naming issues

It seems that there are some issues in the included Coin logs in Qt Safe Renderer.

For example, QSR 2.0 RC4 Coin logs are in this Coin task:

http://coin/coin/integration/tqtc-boot2qt/qtsaferenderer/tasks/1680754036

And when installing the QSR RC4 from staging area, the log zip contains some issues.

For example following path in Windows: D:\QtQSR2.0\Docs\QtSafeRenderer-2.0.0\QSR2.0\Verification_documentation\QSR_Verification_Report\Appendix_Logs\build_logs\qtsaferenderer_buildLogs

Extracting with 7z program (maybe this can be issue?) in Windows

Correct case: 

Folder: Linux-RHEL_7_6-GCC-Linux-RHEL_7_6_Static-X86_64

file: log.txt.gz

Incorrect case:

1) Folder MacOS-MacOS_10_14-Clang-MacOS-MacOS_10_14_Static-X86_64

file: log.txt_

When extracting the file, there is a file log.txt with correct looking content

2) Folder MacOS-MacOS_11-Clang-MacOS-MacOS_11_Static-X86_64-ARM64

file: log.txt_

3) Folder: Windows-Windows_10_21H2-Mingw-Windows-Windows_10_21H2-X86_64

file: log

4) Folder: Windows-Windows_10_21H2-Mingw-Windows-Windows_10_Static-X86_64

file: l

5) Folder: Windows-Windows_10_21H2-MSVC2015-Windows-Windows_10_21H2-X86_64

no files

6) Windows-Windows_10_21H2-MSVC2019-Windows-Windows_10_21H2-X86_64

no files

7) but in folder D:\QtQSR2.0\Docs\QtSafeRenderer-2.0.0\QSR2.0\Verification_documentation\QSR_Verification_Report\Appendix_Logs\build_logs\qtsaferenderer_buildLogs

are files

Windows-Windows_10_21H2-MSVC2015-Windows-Windows_10_Static-X86_6

and 

Windows-Windows_10_21H2-MSVC2019-Windows-Windows_10_Static-X86_6

And those can be extracted with 7z.

Following questions rise

A) Are there issues in compression that causes faults in the decompression in this given environment?

B) Does this occur with other tools than 7z and in other operating systems?

C) Why this occurs and can it be fixed?

D) Are there workarounds ?

E) And what should be informed and where, by whom and when what comes to the possible resolution?
