[GNUnet-developers] gnunet crash using guile

[Amirouche Boubekki]

I have a crash of my program using gnunet-guile. The core seems
to indicate that the crash is in gnunet. Here is the backtrace:

I am using gnunet commit 477e0dec4d6e9a51af2258611f45adea319ff6ae.

The code that crash can be found 
https://gnunet.org/git/gnunet-guile2.git...

Mind the fact that particular code path is the same and doesn't crash in 
the previous
commit of gnunet-guile2.

In the latest version, there is background thread that is running a 
scheduler and
another scheduler that is executed just to do a publish. At the moment 
of the crash,
two schedulers try to run... Long story short, I created a wrapper 
around the async
API of gnunet-guile to execute the code in synchronous way, using guile 
threads.
