[Bug 1970521] Re: [SRU] boinc-client crashes when started with core dump on Xubuntu 22.04

[Sudip Mukherjee]

debdiff attached.


** Summary changed:

- boinc-client crashes when started with core dump on Xubuntu 22.04
+ [SRU] boinc-client crashes when started with core dump on Xubuntu 22.04

** Description changed:

+ [ Impact ]
+ 
+ boinc-client is completely unusable on older CPU which does not have avx like a Celeron CPU.
+ It will crash immediately if run on old CPU, but will run without any problem on newer CPUs.
+ 
+ [ Test Plan ]
+ 
+ It should be done on both types of CPUs, one which has AVX, and one which does not have AVX.
+ If using qemu then "-cpu Conroe-v1" will emulate Celeron CPU without AVX.
+ 
+ Confirm with the command "lscpu" and check the flags if "avx" is listed
+ or not.
+ 
+ Commands to execute for testing on both CPUs:
+ 
+ 1. Install boinc
+ 2. Execute "boinc" from a terminal
+ 
+ If the package is not fixed then it will fail to start.
+ 
+ [ Where problems could occur ]
+ 
+ There is no change in the code and is only modifying debian/rules so
+ that the built binary does not have any machine instruction for AVX. It
+ will result in a different executable machine code but chances of
+ regression due to this is very low.
+ 
+ [ Other Info ]
+ 
+ This change is from Debian and is part of Ubuntu from Manctic onwards. There has been no reported regression due to this change.
+ The Debian change is at: https://salsa.debian.org/pkg-boinc-team/boinc/-/commit/a0611c2bc86864428337b07b382e4d5cf823b95d
