| Run on V4 compiler and not on V5 |

Hi sorry for my poor english i’m french !
I have a compilation problem with one of our application.
We use Pic18f67J10.
The application was build on a V4.112 compiler few months ago.
We update our CCS Compiler in spring to V5.020
With the V4.112 compiler all is OK. The application run perfectly.
With the 5.020 we are seeing an erratic run (we suspect memory crash).
In the source, we are using structure in some structure with different type of data (int1, int8, array of structure etc ….)
We pad the structure int1 to 16 - no effect !
May be some optimization or changes in the two compiler versions make pb
Have you any idea ?
Waiting for a response.
Best regards . |

very early Version 5 did have it's 'problems' I strongly suggest you buy or upgrade to the current version or stay with your known stable version 4,
unless there are specific reasons to upgrade to 5.

If you think that's the problem, post a small compilable test program
that has this structure in it. Then we can compile it and look at the .LST
file for problems.
Other ideas:
1. Read these threads and see if they are related to your problem:
Code made in version 4.114 does not work in version 5.

Strange problem compiler versions.

2. Compile your program with both versions of the compiler.
Do it on different PC's, or do a clean install each time, so you're certain
the correct version files are being used for each compilation. Then
compare the Config Words at the end of the .LST file. Are they the same
for each compilation ? Look at the numbers. There may be something
wrong with vs. 5.020:

didn't you use arrays?
the fact that the crash occurs after some operation make me suspicious.
mis indexing /or over-indexing an array
can cause a crash too!!
and the difference between static mem address thats overflowing
could stem from WHERE and in what ORDER your vars were placed.
that's tougher to figure out .....
anyway
PS: PCM programmer donated an excellent course level 101 in
HOW to THINK about your problem too.
the .LST file comparision is your friend here
on EITHER cause of your trouble.
introduce yourself to it.......

Hi
Thank you to all who responded !
May be i find something !
I use some structure of structure .
When i access the Array of bits named DefF1,DefF2,DefFeux it is the beginning
of the structure (TAFFICHAGE Aff[NBLIG]; ) who is modified.
best regards

NBCARLIG_PHYS |
Your structure doesn't compile if I put it in a test program. It's missing
the #define statements for the constants shown above.

Post some code that shows how you access the array of bits.
I'm trying to make a test program. You should actually do that.
A test program is a small, complete, compilable program that
demonstrates the problem. |

hi
| Code: |
#define NBLIG 1
#define NBCARLIG_PHYS 11 |
I access almost like this :
| Code: |
TFLU Flu;
int1 def; // (result of function)
int8 numfeu;
for (numfeu=0;numfeu<NBFEUXLEDS;numfeu++)
{
// def=func();
def=1
if (def)
{
if (Flu.DefF1[numfeu]==0)
Flu.DefF1[numfeu]=1;
else
if (Flu.DefF2[numfeu]==0)
Flu.DefF2[numfeu]=1;
else
if (Flu.DefFeux[numfeu]==0)
{
Flu.DefFeux[numfeu]=1;
ret=false;
}
}
else
{
Flu.DefF1[numfeu]=0;
Flu.DefF2[numfeu]=0;
Flu.DefFeux[numfeu]=0;
}
}

My boss told me that I have already spent a lot of time with this problem. I have no more time for further investigations.
best regards |
