Thread: malloc + segmentation fault

Could you help me ?

Code:

      //Test part 1
      testInt = (strlen(OpenFiles[fileDesc].filename)+1)*sizeof(char);
      puts(BBuffer[newBufPos].filename);
      //Until here everything works fine


      BBuffer[newBufPos].filename = malloc((strlen(OpenFiles[fileDesc].filename)+1)*sizeof(char));
      //After malloc i get seg fault but arguments have already check by part 1
      puts("********");

      if(BBuffer[newBufPos].filename == NULL)
      {
        BF_errno = BFE_NOMEM;

        return BF_errno;
      }

The segFault appears at malloc.
At first i thought that might be an accessibility problem (violation access) with (strlen(OpenFiles[fileDesc].filename)+1)*sizeof(char) or BBuffer[newBufPos].filename thats why malloc creates segfault, so i made Test part1 .

Test Part1 works fine !!!!!

I print stars after malloc and they don't appear, this lead me to the conclusion that malloc is the suspect.


Can malloc produce a segmentation fault regardless of my given arguments ?
Should i free filename first ?
