libevent and exceptions

[e-t172]

When using the C libevent library 
(http://www.monkey.org/~provos/libevent/), i can't throw any exceptions 
from inside an event callback (trying to do so results in a segmentation 
fault).

Example :

import std.stdio;
import std.math;
import std.date : TicksPerSecond;

import c.libevent; // C bindings, if you want to see them just tell me

void main()
{
     auto base = event_init();

     auto event = new event;

     event_set(event, -1, EV_TIMEOUT, &foo, null);

     int time = 3 * TicksPerSecond;

     auto tv = new timeval;

     tv.tv_sec = cast(int) floor(time / TicksPerSecond);
     tv.tv_usec = cast(int) ceil((time / TicksPerSecond) * 1000000);

     event_add(event, tv);

     event_base_loop(base, 0);
}


extern(C) void foo(int fd, short type, void* arg)
{
     writefln("Boo.");

     throw new Exception("Booboo.");
}

Result :

$ dmd excptest.d c/libevent.d -L-levent -L-L/usr/local/libevent/lib
gcc excptest.o libevent.o -o excptest -m32 -lphobos -lpthread -lm 
-Xlinker -levent -Xlinker -L/usr/local/libevent/lib -Xlinker 
-L/usr/local/dmd/lib
$ ./excptest
Boo.
Segmentation fault

Any ideas how to make this work ?
