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