floating point exception in binary

[Vivek Katakam]

Hi all,

I failed to mention  where the floating point exception occurred.
These are in the following lines.

$ ../bin/dr_End2End
Floating point exception

and when I run through debugger I am getting the following error:
(gdb) run
Starting program:
/home/vkatakam/dstars.2003.1.0_new/src/report/dr_End2End/bin/dr_End2End

(gdb) list
189       istat = (int) StartLogger(&sLogSetup, argv);
190       if (istat != 1) {

I want to know is this due to sofware or hardware error .

Regards,
Vivek
