Hello:
I've got a weird problem with getmem. I have check everything (i think) but i can't get it work. Heaptrc says it's all ok, but when i de-comment the next three lines ( the freemem also ), all fails

      GetMem(sDicc,sizeof(rtBusqBidimen));
      GetMem(ppmv,sizeof(rtMotionVector));
      GetMem(nDicc,sizeof(rtBusqBidimen));

      if (sDiccnil) AND (nDiccnil) AND (ppmvnil) then
         writeln('MAS MEMORIA PARA VECTORMOTION') // Chequeo de memoria

INICIAL
{More Memory for VECTORMOTION //NITIAL memory check} else begin
......

The sizes are 14,8,14, MemAvail says near 48Mb and MaxAvail 47'5. I tried to put them in the program vars (they are in a function), change the sizeof (which print on screen 14,8,14) to it's values re-type for a misspelling error. Their declartions at var are

nDicc,sDicc       : prtBusqBidimen;  // p= point r= record t= type BusqDimen
ppmv                 : prtMotionVector;  // id. MotionVector

When skip the if (sDiccnil)... a runtime error 201 appears

what's the next step??

Any clues??

TIA

Eduardo,

I did not follow your example, but are you aware of the "growing heap" behavior of FreePascal and the ReturnNilGrowHeapFails variable?

http://www.freepascal.org/docs-html/prog/progsu113.html#x163-1680008.4

Also, I think this ReturnNilGrowHeapFails behavior is broken in 1.0.6 and fixed in 1.0.7 (which, I think, is not available yet).

But I don't know why you get RTE 201? (You should be getting 203 or 216 or something)

I just looked at this again. If you are really getting RTE 201 then it (probably) has nothing to do with the GetMem's. It means you are over-indexing your arrays or seomthing similar. Good luck.

That's what surprise me, so rechecked and yes, the rte is 201. I get the error when i don't check them for nil. If i chek the nil, the program never enters in the code. I use them to navigate throught lists structures defined as global. As said, if i define them as global too i get.... the GetMem works!!!... and the rte 201 apears again. Perhaps i use them badly, but the main problem for me was the not allocation of memory for them.

Also i use fpc 1.08

Thanks

Is 1.0.8 available? I just checked www.freepascal.org and it seems like 1.06 is the current release. You might try that version and see if the problem goes away.

1.07 and 1.08 are updates to 1.06. You must download them and install by hand. In a few weeks (accordlying to a previous post) 1.08 will be out.

This sounds like some memory corruption is going on in your program. There are unfortunately no really easy ways to find out where this happens.
