Parity-Ethereum version >= v2.1.1 fails to start on windows.

[fevo1971]

• Parity Ethereum version: 2.1.1
• Operating system: Windows 10 Pro
• Installation: official binary and built from source
• Fully synchronized: -
• Network: -
• Restarted: -

Tested with binary release from
https://github.com/paritytech/parity-ethereum/releases/tag/v2.1.1
as well as fresh build from master on my local machine.

actual
When starting parity.exe (with or without command options)
immediately returns to the command-prompt without any output.

expected behavior
starting parity.exe should start a node / display version when started with --version / --help

/cc @andresilva can it be related to the segfault in rocksdb?

@fevo1971
If you can give me access to the machine or show me in the office next week I can help investigate this!

[jam10o-new]

any chance this is related to #9624 ?

[ordian]

Can also be related to #9684

[andresilva]

Is it possible to build a binary from latest master on that windows machine? If that binary also fails then we know it's not related to #9684.

[andresilva]

Now that I think of it, issue #9684 should be GCC/LLVM specific and shouldn't affect the Windows build.

[ordian]

On Windows it uses /arch:AVX2 flag in release build of v2.1.1, so if the CPU is older than Haswell (Q2 2013), it will fail with illegal instruction.

[ordian]

if the same applies to 2.1.2-beta, then it was unrelated to #9684

[Tbaut]

That's been fixed right?

[Tbaut]

it's solved :)
