| Affected Platform/Device: | default |
| Workaround: | Use -Ooff to turn off the optimizer, or ensure that only size_t variables are used as the count argument to memcpy(). |
| Release Notes: | Calls to memcpy which use an expression of an integer type smaller than size_t for the length argument may fail to zero-extend the value to size_t, which may result in the length value seen by the memcpy function to be garbage. |
| Description |
|
Calls to memcpy which use an expression of an integer type smaller than size_t for the length argument may fail to sign- or zero-extend the value to size_t, which may result in the length value seen by the memcpy function to be garbage. |
