I've got some news regarding this.
(my previous post about this can be read here
xemacs uses internally a SIGIO handler to check for ctrl-g key combination. The
handler is clean, in the sense that it only sets a couple a global integer
a/ I can suppress the crashes if I remove completely the SIGIO handler.
b/ The crashes come back as soon as I enable *an empty* SIGIO handler
(i.e. an empty function binded to SIGIO)
Are there any known problems with SIGIO on SMP systems?
