I can't reproduce on my system with:

#include <allegro.h>
#include <string>

int main(void)
{
   allegro_init();

   string setting = "flip_pan = 1";
   override_config_data(setting.c_str(), setting.length());
   reserve_voices(6, -1);

   allegro_message("1");

   if (install_sound(DIGI_AUTODETECT, MIDI_AUTODETECT, 0))
   {
      allegro_message("Failed to install sound. Allegro error: %s",
         allegro_error);
   }

   allegro_message("2");

   return 0;
}
END_OF_MAIN()

Could you try to find where Allegro crashes with a debug version run from
GDB ?

What happens if you comment you the lines between allegro_init() and the
first allegro_message() ?
