--- Comment #10 from noabody@yahoo.com --- Problem is in: $HOME/.wine/drive_c/Program Files (x86)/KeePass Password Safe 2/KeePassLibC64.dll
Rename file to: $HOME/.wine/drive_c/Program Files (x86)/KeePass Password Safe 2/KeePassLibC64.bak
And keepass2 starts normally. Any version of keepass downloaded from official channels has a very different layout than if built locally, whether via mono or vs2017. Official builds look like this:
KeePass.chm KeePass.exe KeePass.exe.config KeePassLibC32.dll KeePassLibC64.dll KeePass.XmlSerializers.dll License.txt ShInstUtil.exe
Personal builds look like this:
KeePass.exe KeePassLib.dll KeePassLib.xml
Pretty big difference. Not real sure why that is but all of the personal build I did looked like they were "AnyCPU" or combined architecture, which might just default to non-64bit. Presumably KeePassLibC64.dll wants to use enhanced CPU instructions, wine bycrypt advertises their availability, gnutls provided the capability, and the CPU cannot process.
I like to think of the K10 cpu instruction set deficiency as:
Keepass wants it (one of the following SIMD/SSSE3/AES-NI/AVX/SSE4.1) Wine says it has it gnutls provides it cpu fails to process it
