Bug#903514: Deadlock in _dl_close join-ing threads accessing TLS (was Re: gimp won't launch)

[Jackie <jiangjun12321@gmail.com>]

Great. It works. 

To make it clear, this is what I did to test:

1. Install libopenblas-base:amd64 (0.3.2+ds-1) and libopenblas-dev:amd64 (0.3.2+ds-1) from official repo. After installation complete, open a terminal and type gimp + ENTER. The cmd hangs forever and Ctrl-C gets a segment fault.

2. sudo apt purge libopenblas-base libopenblas-dev. Upon finish, open a terminal and type gimp + ENTER. Gimp lanuches without problem.

3. Add the repo you offered and install libopenblas-base:amd64 (0.3.2+ds-1.1~1patchTLS) and libopenblas-dev:amd64 (0.3.2+ds-1.1~1patchTLS). The installations go well, after that, open a terminal and type gimp + ENTER.  Gimp again lanuches without any problem.

I think this validates both the existence of the bug and your solution. Thank you very much.

I can provide a binary package that include this patch, but I'm not sure this is the best thing to do (I'm not the official maintainer, nor know a good place to upload it).

As I was requested to provide binary package to test the patch, I'm providing this as version `0.3.2+ds-1.1~1patchTLS` built with sbuild at [0]. Instructions are on the same page [0]: execute: `apt-key adv --keyserver hkps://hkps.pool.sks-keyservers.net --recv-keys 0x3F7A2FA142E434FE06622560B05266B2EB68F001` and add `deb https://amurzeau.github.io/apt-repository unstable main` to sources.list. This APT repository contains both the source and amd64 binary packages. If you try it, please tell if it works. [0] https://amurzeau.github.io/apt-repository/
