Hello,

I have encountered the code below in the application I'm migrating :

PROGRAM PRG1

SUB PRG2

As you can read the programs above :
- the caller sub declares a variable of 2000 bytes
- the callee sub declares the same variable of 16000 bytes through the linkage section and a working variable of the same length

The only action made is to copy the value from caller variable to callee variable :
The translation in C language for the line

is

that is syntactically correct
but the real length of b_7 is 2000 not 16000 so an exception is risen "Attempt to reference unallocated memory (Signal SIGSEGV)" (OC 1.1) / "Memory Fault" (OC 0.33)

I understand that this issue (maybe someone has already written a post about this problem but I haven't found any) is due to the asset i'm working on but could the problem and the solution may lie between using the cob_module structure and the cob_move function, as when the move action between two variables of different lengths is done by the cob_move function ?

KR,
