The sample code below will produce the following internal compiler
error when compiled with both /Oi and /Oe optimizations:
sample.c(10) : fatal error C1001: Internal Compiler Error
(compiler file '@(#)exphelp.c:1.115', line 391)
Contact Microsoft Product Support Services
The following are several workarounds to this particular internal
compiler error.
1. Avoid using the optimizations /Oi and /Oe together.
2. Insert the #pragma optimize statement into the code to turn off the
offending optimizations for the particular function.
3. Use temporary variables to simplify the expression on line 10.
Sample Code
-----------
1: #include <math.h>
2: void main(void)
3: {
4: double x, y, z;
5: struct {
6: double d;
7: } data;
8:
9: z=2.0 * x;
10: data.d=(2.0*x) / sqrt( pow(2.0-y,2) + pow(z,2) );
11: }
Microsoft has confirmed this to be a problem in C version 6.00. This
problem has been corrected in version 6.00a.
