Runtime checking prints the following information for memory access errors:
Error |
Information |
---|---|
type |
Type of error. |
access |
Type of access attempted (read or write). |
size |
Size of attempted access. |
address |
Address of attempted access. |
size |
Size of leaked block. |
detail |
More detailed information about address. For example, if the address is in the vicinity of the stack, then its position relative to the current stack pointer is given. If the address is in the heap, then the address, size, and relative position of the nearest heap block is given. |
stack |
Call stack at time of error (with batch mode). |
allocation |
If the address is in the heap, then the allocation trace of the nearest heap block is given. |
location |
Where the error occurred. If line number information is available, this information includes line number and function. If line numbers are not available, runtime checking provides function and address. |
The following example shows a typical access error.
Read from uninitialized (rui): Attempting to read 4 bytes at address 0xefffee50 which is 96 bytes above the current stack pointer Variable is ”j’ Current function is rui 12 i = j; |
