EVP_aes_128_ctr entry point not found

[Chocobo1]

I downloaded PortableGit-2.5.2.2-64-bit.7z.exe on Windows 8.1 x64, and extract it at C:\Git.
Then I issued git fetch on my qbittorrent git repo, the error occurs and git crashed.

Here is a screenshot:

Translation:

The procedure entry point EVP_aes_128_ctr could not be located in the dynamic link library C:\Git\mingw64\bin\libssh2-1.dll

How can I reproduce this?? I.e. what is the URL I need to clone to experience the same error?

I am not sure if you could reproduce this, anyway here is the info:

git remote -v
origin  https://chocobo1@github.com/Chocobo1/qBittorrent.git (fetch)
origin  https://chocobo1@github.com/Chocobo1/qBittorrent.git (push)
upstream        https://github.com/qbittorrent/qBittorrent.git (fetch)
upstream        https://github.com/qbittorrent/qBittorrent.git (push)

Unfortunately, I cannot reproduce:

$ git clone https://chocobo1@github.com/Chocobo1/qBittorrent.git

Just Works. Maybe you have a strange proxy sitting in front of the internets?

I found out it's my fault. It works correctly when I double-click and install it (using the bundled sfx extractor).
My previous attempt was using 7-zip 15.05 beta x64 right-click menu -> extract to..., obviously that broke something... sorry for the noise.

@Chocobo1 ah! The post-install.bat script!

Thanks for the reminder; I really need to mention this in README.portable.

BTW, a suggestion:
looking at https://github.com/git-for-windows/build-extra/blob/master/portable/release.sh#L30

it might be possible to change -m0=lzma to -m0=LZMA2
Here is from the 7z document:

LZMA2 is modified version of LZMA. it provides the following advantages over LZMA:
Better compression ratio for data than can't be compressed. LZMA2 can store such blocks of data in uncompressed form. Also it decompresses such data faster. 
Better multithreading support. If you compress big file, LZMA2 can split that file to chunks and compress these chunks in multiple threads.

it might be possible to change -m0=lzma to -m0=LZMA2

Could you compare the size before and after this change?

Seems LZMA2 is a bit larger :\
