Incorrect memcpy Call
Occurs when an application calls the
memcpy
function with two pointers that overlap within the range to be copied. This condition is only checked on Linux* systems. On Windows* systems, this function is safe for overlapping memory.
ID | Code Location | Description |
|---|---|---|
1 | Call site | Represents the location from which the memcpy function was called. |
Example
char *p = (char *)malloc(10); memcpy(p+3, p, 5);
Linux* operating system/GNU gcc* compiler: The
Intel Inspector
cannot check for inlined calls to memcpy
. Specify -fno-builtin
to prevent inlining and allow the Intel Inspector
to check for arguments.Possible Correction Strategies
If the arguments represent the range you want to copy, call the
memmove
function instead of the memcpy
function.
