Re: Crashing in 32-bit but works on 64-bit

Hi Mitesh,

with the information you gave as we can't say anything -- just guess.
There are many possibilities:
 - sizeof(int) might be different for 32 and 64bit -- maybe you have
   some overflows?
 - it might be that you mix different types, like: "size_t" and "unsigned
   long" might be the same on one system, different on the other
 - it might be a bug in CentOS or gcc
 - it might be a Hardware-bug of your processor (if some vector units
   have problems, which are only used by your code in 64bit-mode;-)
   Well, that's VERY VERY unlikely :-))
 - ....

For any reasonable tips, we need a SMALL example code, which reproduces
the bug...
