Gopi can you give the reasoning? All your alloc 's are wrong. If you're allocating an array of X, then you'll be assigning the result of Add a comment.
Active Oldest Votes. Gopi Gopi When you compiled, you should have seen a warning like this: with a different filename, of course badrealloc. Got the output. And added the usual warning about memory leaks and realloc. Sorry if it was confusing. Stephan Stephan 8 8 silver badges 22 22 bronze badges.
It's not the compiler complaining about malloc. It's the debugger complaining about malloc. By the way, glibc includes a malloc.
See man mallopt. In this case, it is not necessary, of course. Sign up or log in Sign up using Google. Sign up using Facebook.

Something must be different about your system. Now we need to figure out why. What version of Xcode are you using? I'm using 2. Please update if you have anything earlier than 2. These can interfere with MacPorts and should be removed if present. Bin Lu. I keep getting this malloc problem when my program tries to allocate memory for some pointer.
Any idea what this is about and how to solve it?? I'd appreciate it very much if you can give me a hint!! Follow Post Reply. Dave Vandervies. It goes through the function with this statement several times and seems that it has successfully allocated the memory. Most likely, you're scribbling over memory that malloc and friends use for their internal bookkeeping or doing something silly like trying to free the same pointer twice.
Go through your code carefully and make sure that: -Everything that fgets mallocd fgets freed exactly once -Every time you dereference a pointer into mallocd memory, it's inside the size bounds passed to malloc originally -You don't try to dereference[1] any pointers into mallocd memory you've already given back to free My guess would be that in the process of doing so you'll find and hopefully fix a few bugs and, as a result of that, the problem is likely to go away.

Based on your snippet, you don't seem to be checking whether malloc fails. You should. Andre, creep Andre, creep. That's a typical symptom: you got memory corruption somewhere in your program e. Stop looking for the error in the call of malloc and check everywhere else for problems. Better, get a memory debugger and let it help you figure out where exactly the s..
If the program isn't too long you can also post it here. Eric Sosman. Erik de Castro Lopo. This is almost certain, your program corrupting heap memory. There are probably ways to do this, including writing past the end of a buffer, incorrect array indexing and so on.
