I've had this same problem. You might notice as well that the memory on the Pro*C process grows and grows. I had it over 200 MB at one point. What I did to fix this was to make sure proc didn't read the standard include files. (Check out the ORA_PROC macro, or the parse option.)

Another symptom of the switch from 4.2 to 5.0 is that compiling takes *MUCH* longer.

I put all this together and suspect that there's an infinite loop somewhere in the include files in 5.0. The CC compiler is smart enough to eventually detect this and break out of it, but proc isn't. Just a guess.

Cheers,
Jim
