[Mesa-dev] Let's enable _GLIBCXX_ASSERTIONS=1 on mesa debug builds

[Timur Kristóf]

Hi,

We've been recently working on tracking down some "mysterious" crashes
that some users experienced on distro builds of mesa but we couldn't
reproduce locally, until we found out about _GLIBCXX_ASSERTIONS=1 which
seems to be not enabled by default in mesa, but is enabled by a lot of
distros.

I realize that enabling it by default on all mesa builds would have
performance implications, so I propose to just enable it by default in
mesa debug builds.

What do you think? Would this be okay with the mesa community?

Thanks & best regards,
Timur
