Possible g++ problem. isnan signals
FPE invalid operation when given a NaN.
(Ditto isnanf. I found that using g++ 4.1.2, where isnan
works but isnanf signals FPE invalid operation, not shown.)
If not g++ problem, any advice on which other .org
to report problem to would be much appreciated, 'the
assembler, the linker or the C library', etc. Thanks.
Command line
% ( g++ -v -c -g -m64 -Wall -fpic -save-temps -o check4nan.o check4nan.cc ;
g++ -m64 -shared check4nan.o -o libnan.so ;
g++ -c -g -m64 -Wall -fpic -save-temps -o nan.o nan.cc ;
g++ -m64 -L. -lnan -o nan nan.o ;
setenv LD_LIBRARY_PATH .:${LD_LIBRARY_PATH} ;
./nan )
