STRANGE SEGFAULT

[Toni Moreno Giménez <toni moreno gimenez wanadoo es>]

Hi.
When debugging my application, gdb shows the following backtrace:

Loaded symbols for /usr/lib/gtk/themes/engines/libraleigh.so
#0  0x40485f84 in __libc_write () from /lib/i686/libc.so.6

The code "seems" ok, so I have tested diferent solutions, in the last, I have 
decided to lock memory using mlockall(), when using it, application runs ok, 
I have no much experience on direct system call programming so I can't 
understand this segfault. 

The application is running 2 threads , the first for the gtk_main loop, and 
the second runs a sound  writer to /dev/dsp loop.

Somebody can help me? please ?

Lots of thanks.
