bzip3-x86_64 crashing on Windows 7

[Erol-2022]

Hello,

Thanks for the new release of bzip3.

Testing v1.3.0, bzip3-x86_64.exe is crashing on Widows 7. The error message is :

A problem caused the program to stop working correctly. Windows will close the program and notify you if solution is available.

bzip3-i686.exe does not have this problem.

Hello! As I am no longer a Windows user (as of many years now!) it will probably be a while until I get a Win7 VM and then figure out how to debug this.

My first guesses: what is your processor, how much RAM do you have?

Hello,

Thanks, hardware is not the cause as the processor is Core i7 and the memory is 6 Gb.

My practical solution is to rebuild the executable with Msys2 :

./configure CC=x86_64-w64-mingw32-gcc --host x86_64-w64-mingw32 --enable-static-exe
make

Now, the new executable does not crash on Windows 7.

So the hardware is indeed the cause. This is a dupe of #99. This is fixed on the main branch and the new executables will be built when v1.3.1 is released.

&"C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.28.29910\bin\Hostx64\x64\dumpbin.exe" /NOLOGO /DISASM .\bzip3-x86_64.exe | Select-Object -Skip 5 | Select-String -Pattern '.{39}(?<instruction>\b.+?\b)' | % { $_.Matches[0].Groups["instruction"].Value.Trim() } | ? { ![string]::IsNullOrEmpty($_) } > ins.txt

Then:

$ sort i.txt | uniq

Lists the instruction vcvtusi2sd coming from AVX512-F, which your CPU can't have.
