This program crashes inside printf of a pseudo-zero 'long double' number.
============================== ia64nan.c ================================
#include <float.h>
#include <math.h>
#include <stdio.h>
union u { unsigned int word[4]; long double value; };
#define X x.value
void test (const char *label, union u x)
{
printf ("%s:\n", label);
printf ("isnanl: %d %d %d\n", isnanl(X) != 0, !(X == X), !(X >= 0 || X <= 0));
printf ("isinfl: %d %d\n", isinfl(X) != 0, X + X == X && !(X == 0));
printf ("printf: %Le %Lg\n", X, X);
printf ("printf normalized: %Lg\n", X * 1.0L);
printf ("\n");
}
int main ()
{
{
union u x = { { 0x00000000, 0x63333333, 0x00008000, 0x00000000 } };
test ("unnormalized number", x);
}
{
union u x = { { 0x00000000, 0xC3333333, 0x0000FFFF, 0x00000000 } };
test ("QNaN", x);
}
{
union u x = { { 0x00000000, 0x83333333, 0x0000FFFF, 0x00000000 } };
test ("SNaN", x);
}
{
union u x = { { 0x00000000, 0x80000000, 0x0000FFFF, 0x00000000 } };
test ("Inf", x);
}
{
union u x = { { 0x00000000, 0x40000001, 0x0000ffff, 0x00000000 } };
test ("Pseudo-NaN", x);
}
{
union u x = { { 0x00000000, 0x00000000, 0x0000ffff, 0x00000000 } };
test ("Pseudo-Inf", x);
}
{
union u x = { { 0x00000000, 0x00000000, 0x00008004, 0x00000000 } };
test ("Pseudo-Zero", x);
}
return 0;

Segmentation fault
According to
Intel IA-64 Architecture Software Developer's Manual, Volume 1:
Application Architecture.
5.1.3 "Representation of Values in Floating-Point Registers"
Table 5-2 "Floating-Point Register Encodings"
Figure 5-11 "Floating-Point Exception Fault Prioritization"
pseudo-NaNs, pseudo-Infs, pseudo-zeroes "are never produced as a result
of an arithmetic operation", i.e. they may be considered to live outside
the IRRR 754 range of numbers. But it would be nice if printf would not
crash here, because
1) printf is often used for debugging. This is also the reason why
printf("%s", NULL) prints "(null)" instead of crashing.
2) Arithmetic operations on pseudo-NaNs, pseudo-Infs, pseudo-zeroes
don't cause program crashes, if operations on "signalling NaNs"
don't cause program crashes (see Figure 5-11, cited above); this
is the default behaviour, as you can see from the program's output.
Additionally, the printf results for pseudo-NaN and pseudo-Inf should better
be "nan", because these numbers behave like NaNs in comparisons, as you can
see from the program's output.
For comparison: On FreeBSD/ia64, printf of pseudo-NaN, pseudo-Inf, pseudo-zero
yields "nan", "[-]inf", "[-]0" respectively.
