My background and how it can be leveraged

I am a Blockchain Developer

How I plan on tackling this issue

@enitrat Can I work on this, please? This is how I plan to approach the issue:

• Review the test case to understand the conditions under which it fails.

• Investigate the type conversion issue occurring in the mcopy_memory_expansion function.

• Trace the error back to its source and check if there are incorrect or unsupported type conversions happening.

• I will modify the code to ensure proper type handling and conversion, particularly in memory expansion and data copying operations.
  Test the Fix:

• Re-run the test to verify if the type conversion error is resolved.
  Ensure that the fix does not introduce any new issues.
