nvc segfaults while generating the coverage report

[yikkrubz]

After elaborating UVVM-based testbenches with coverage enabled works (Thank you for fixing this issue), nvc asks me to file a bug report while creating the coverage report .

For example, generating the coverage report for the testbench uart_vvc_demo_tb, included with the UVVM distribution in the directory bitvis_uart, triggers the message. I installed uvvm running nvc --install uvvm.

nvc -c --report=report work/_WORK.UART_VVC_DEMO_TB.elab.covdb Note: Code coverage report folder: report. Note: Code coverage report contains: covered, uncovered, excluded coverage details.

I fixed the crash and also reduced the number of warnings to one per file.
