This version still uses malloc() within signal handler which is evil. I see still random hanging build processes and all of them show the same problem: malloc() within a signal handler[1]. Beside this: it is not possible to use the glibc malloc(). IMHO there have to an other way to get the siginfo_t informations from the signal handler down to the normal ksh process flow.
