webdis breaks in SUBSCRIBE command

[cloudgen]

When I have been running the javascipt form README.md to subscibe, the webdis stopped.

The Backtrace is as followings:

*** Error in `./webdis': free(): invalid next size (fast): 0x00007f0a60008f50 ***

Thanks for reporting this issue! Would you happen to have a bit more context maybe? How can I reproduce this crash? What request did you make?

@nicolasff, I've seen folks mention it in https://github.com/anapsix/docker-webdis/issues/2 I've described a way to reproduce it in https://github.com/anapsix/docker-webdis#known-issues

I've attached a valgrind output. Steps:

• Issue the following command curl http://127.0.0.1:7379/SUBSCRIBE/hello
• Cancel by Ctrl+C
• Cancel valgrind by Ctrl+C

Before hitting Ctrl+C on curl valegrind does not have any errors.

valgrind_webdis.log

Edit: I've just check webdis 0.1.3. It does not crash, but it still does not work and produce the same errors in valgrind
