Reduced test for float-cast-overflow-10.c
Test for the float-cast-overflow-10.c failure.
This snippet should detect that _Decimal32 doesn't fit in a signed 64-bit
integer (either signed long or signed long long). Test uses "-m64 -O2
-fsanitize=float-cast-overflow -fsanitize-recover=float-cast-overflow".
If you compile and execute this preprocessed file, does ubsan generate messages
or not?
