Research direction
Investigate RetDec's 32-bit x86 calling-convention identification, using the reported fastcall example as the starting reproduction. Trace how register-based arguments are classified and confirm the fix by ensuring fastcall functions do not access uninitialized argument registers before loading values from memory.
