Bug#145622: process crash on SIGFPE

Package: hurd
Severity: normal


I found a weird problem with exception handling. The following
code generates a SIGEFP exception (overflow), but instead of exiting
with 01 as it should, it will crash:

long foo(long i, long j);
int main() { return foo(LONG_MIN, -1l) && 1; }
long foo(long i, long j) { return i / j; }

note that this equaly functional lines exit properly (with error):

int main() { return (-2147483647L -1) / -1l && 1; }
