Coverage reports fail to generate with LCOV 2.x

[nicholasphair]

LCOV version 2.0 was released earlier this year. It is now the default version distributed by homebrew.

It seems tipc is incompatible with version 2.x. bin/gencov.sh leads to errors.

$ ./bin/gencov.sh

Downgrading to version 1.x fixes the error.

Portal currently provides 1.14.

$ lcov -version
lcov: LCOV version 1.14
