[SerenaC94]

bambu test_issue.c --top-fname=test_function --simulate --generate-tb=test.xml --compiler=I386_CLANG10 -v4 -> synthesis and simulation work fine

bambu test_issue.c --top-fname=test_function --simulate --generate-tb=test.xml --compiler=I386_CLANG12 -v4 -> testbench generation fails with the following error:
