Hello All,

I got a strange problem in that when I run a small program which does
the following :
	int u1 = 350, u2 = 207, v1 = 296, v2 = 408;
	printf("%lf\n", atan2((double)(u1-u2), (double)(v1-v2)));

it works fine, but when I try to do the same thing in a very large
program, the program crashes giving the following dump.

Floating point exception at eip=26b79
eax=00000122 ebx=7ffffc0f ecx=00000000 edx=00000000 esi=7fffe891 edi=0000000e
ebp=7fffe824 esp=7fffe7bc cs=d8 ds=48 es=48 fs=48 gs=38 ss=48 cr2=00003076

  0x000265a6
  0x00024b28
  0x00023ae5
  0x00022218

Would it be possible for some one to tell me what the problem is ? ( I am
using a 486PC. The code runs fine under unix ).

Thank you very much,                                        Q Q  \)
