malloc and calloc in Linux

[Pippo]

I've a problem with linux redhat 9.0 and malloc or calloc.
Sometimes when I throw to allocate memory with calloc or malloc the program
stop (in the sense of infinite cycle) and the call to these function don't
return. How can I understand the reason? Why only sometime the malloc don't
return?(the are a lot of free memory in the pc)

The fact that you're running Linux not relevant here (and if it is
it's off topic anyway).

Please post the smallest possible compilable, runnable snippet of
code that exhibits this problem; otherwise, all we can suggest is
that you have a bug on the dreaded line 42 (or was it line
37...whatever).

HTH,
