Hi,
I'm using directfb v1.4.11 with an embedded device.
When I try to run a program I get signal 4 & 11 and the program is in a
blocking state. I can't even kill it with 'kill -9'.
I saw on the mailing list some people getting the same issue and trying
to disable the keyboard and mouse modules but in my program I don't call
any functions regarding input devices.
I attach my source code.
I get the same issue with all the directfb programs (df_dok, df_andi,...).
If I run one those program (or mine) using gdb, everything works fine
and then I can run my program without using gdb after.
Here is the output when I run my program:
