Package: guile-1.6 Version: 1.6.8-10 Severity: normal
While playing with guile on my system, I discovered a weird anomaly which I could not reproduce on other systems running guile. If I install a signal handler for SIGALRM, it won't get called while guile is making an I/O system call. To demonstrate: [atehwa@karaihin ~/proj/psyk]$ guile guile> (alarm 2) 0 guile> Herätyskello [atehwa@karaihin ~/proj/psyk]$ guile guile> (sigaction SIGALRM (lambda (x) (display "now!") (newline))) (0 . 335544320) guile> (alarm 2) 0 guile> now a lot more than two seconds has passed, while I wrote this now! <unnamed port>: In expression now: <unnamed port>: Unbound variable: now ABORT: (unbound-variable) [...] As you can see, the signal handler gets called as soon as guile returns from read(2), already before calling (eval). I can't get to understand what causes this on my system, because another Debian system with exact same versions of guile-1.6, libc6 and libguile-ltdl-1 seems to work fine, and interrupts the read(2) call with the signal handler.
