Problem with strcpy, gcc4-0, mac OsX?

[julie25]

Hi,

I am developing in C on mac OsX.

I recently downloaded the new version of gcc (gcc4-0) and I have a problem of execution on the following code.

It seams that the use of strcpy have action on the memory and modify the value in the lieu variable (variable of the loop)

I tried on other computers with other versions of gcc and it functions well.
Does anyone know about such a problem?

Thank you very much for your help

for (lieu=0 ; lieu<nb_lieu ; lieu++)
  {
    printf("\n lieu %d \n",lieu); // print 0, 1, 2, 3...	OK
    convert_lieu(lieu,chlieu); // this function does not affect lieu, 
                                          // just put in chlieu the adequate value
    printf("\n lieu %d \n",lieu); // print 0, 1, 2, 3...	OK

    /****** HERE ******/
    strcpy(ch, "\n Blablabla ");
    printf(" %d \n",lieu); // print enormous values
    /************/
    strcat(ch,chlieu);

   }

How is your variable ch defined?
Maybe it is too short to hold the string "\n Blablabla " ?
(And some compilers are more forgiving than others.)

That's it!
