¿Cómo enviar un "backtrace"?
« on: April 15, 2004, 01:15:13 AM »
Esta es la cuestión.
->Cojo la explicación para enviar "backtraces".
->Compilo amule (2.0.0rc2) con las opciones -enable-debug --disable-optimise
->lanzo el amule con el gdb debajo.
->el amule se cuelga, pero no da un "segfault". La interfaz "se queda en blanco", sigue consumiendo CPU pero no descarga nada, y las conexiones que muestra el netstat estan "CLOSE_WAIT"
->no hay manera de tracear. El debuger tiene capturado el proceso.

## Resumen: Necesito saber, de verdad, como enviar un "backtrace" cuando el amule se cuelga, sin dar un segfault.

## Características
Debian sid con amule compilado con las opciones -enable-debug --disable-optimise. Si lo compilo de otra forma el error es el mismo.
