Under Linux, gcc/g++-compiled code happily continues running after
producing NAN and INF. Often it is time-consuming to backtrack to the
actual source of the numerical problems. In addition, such problems may
go undetected for some time, which can cause all kinds of confusion.
Other
platforms stop after a floating-point exception (e.g. HP's Tru64 Unix
with cc/cxx), or support customizations of FPE behavior via environment
variables (e.g. SGI's old IRIX). Is something like this possible with
gcc/g++ under Linux?
Thanks!
