Recently I used DJGPP to write a fairly large graphics program. Everything is normal when it first runs (including floating-point operations), but after it runs for a while, an exception occurs saying the coprocessor cannot be accessed. The runtime before the exception is not fixed, but when the exception occurs, the IP value is always the same. When the program terminates, it shows that both the CS and SS selectors are invalid.
Machine specs: CPU: Cyrix MMX-S 233 Memory: 128M Hard disk (electronic disk): 32M Could some expert help analyze what the problem is? I've been struggling with it for nearly a month and still have no clue at all. 3X |

How about trying an Intel processor instead~

Hehe, since the product has already been finalized, changing the processor is basically impossible.
 Is there any other way? |

Just this much (brief) information? Even if others want to help, they can't.

There are two possibilities:
1: There may be some errors in the program itself; 2: The DJGPP version being used is too old, you can try updating it. |

1, The program runs without any problem on a PII350 machine; I don't know whether this can rule out a problem with the program itself;
2, The DJGPP version I'm using is 2.01. I don't know what the latest version is, or where to download it? |

It may be that you are repeatedly calling the graphics-reading function, causing a memory overflow.
