| 16 | If ltrace's target command has a dbg package, ltrace will look for the debug file and analyze its contents. |
| 17 | Ltrace determines the type of analysis result variable. The type of the variable is longlong. |
| 18 | On 32-bit systems, longlong is 8 and long is 4 (same as in). |
| 19 | An error occurred because the ltrace code did not process a variable of length 8. |
