Error 251 (according to [1], but probably also for C++) is "signal
received"), which fits the line above. Signal 9 is a hard kill. This,
and your statement "a while" suggests that the compiler was killed -
likely by a script on the cluster head node that kills all processes
that take "too long". Computing centers sometimes do this to prevent
users from running compute jobs on the head node. Unfortunately,
sometimes compiling can also take a long time, and scripts usually don't
differentiate. Could this be the case? How long was "a while"? Would it
work to compile inside a compute job - at least to test that theory?
