[Bug fortran/32153] runtime integer overflow checking fails

[burnus at gcc dot gnu dot org]

-ftrapv only traps floating-point overflow - no integer overflows.

(This is not completely correct, as some systems seem to offer to send FPE also
for integer overflows, see e.g.
https://www.cisl.ucar.edu/docs/ibm/ref/fpe.html
For x86 (32/64) platforms, this does not seem to be directly supported by
hardware; in this case one would need to add manual checks, which are slow, cf.
e.g.
http://softwarecommunity.intel.com/isn/Community/en-US/forums/thread/30227217.aspx
.)

-> WONTFIX, unless you find a good method to trap integer overflows.
