I have proposed in the latter that you switch the port to using a newer
GCC version or clang on the affected systems, to sidestep the issue.

I am unsure if we will have an erratum, so for the benefit of users who
use the releases rather than STABLE/, it would be beneficial to have the
port compilable on systems that installed a broken/unpatched gcc 4.2.

Dimitry, any plans for an erratum?

Thank you.
