Hi,

Iam getting an error regarding ldiv.c. I gave a global search and i was not able to find this ldiv.c file anywhere. While executing the program Iam getting a core as follows

Program terminated with signal 8, Arithmetic exception.
FPE_INTDIV - integer divide by zero
#0 0x60000000c5347060:2 in _div32I () at ldiv.c:558
558 ldiv.c: No such file or directory.
in ldiv.c
(gdb) bt

Please help me in this regard.

Thanks,

I'd forget about ldiv.c, which sounds like
part of a system library, and worry about
line 6702 in common.c, where you appear to
be trying to divide something by zero.

That's close. Look for "nan" (not a number)
in /usr/include/math.h.

The error you are getting is a divide by zero, which is being detected in the library module _div32l, the source file for which just happens to be ldiv.c. Since you don't have the source for the library module, gdb can't find it. This is not an error.

You need to look at the calling code to determine why zero is being passed.

Not quite. When you divide non-zero by 0, you get an INFINITY. :-)

Yes, this is defined in /usr/lib/hpux##/milli.a.
