Re: [PATCH] gcov: Add block_info::block_info (PR gcov-profile/80911).

Hello.

Following patch adds default constructor that initializes all fields in block_info.
Which fixes the 77 corrupted gcno regressions that currently show up when compiling trunk with g++ 4.4.3. 


Patch can bootstrap on ppc64le-redhat-linux and survives regression tests.

Ready to be installed?


Ping.

Thanks,
