Fiddlesticks. So much for the "I'm pretty sure" angle. Yes, it would
have been the most obvious syntax to try, and yes, it indeed appears to
get through the build with the current code base at least when using the
non-const variant for specialization (while I arrived at a binary
previously, it crashed right in post-link stages of the build due to the
sketched initialization problem).
Ok, I'll now see whether the build works even when using const
qualifications in the initialization code. But whether or not IÂ may
find something there, libstdc++ clearly would seem off the list of
possible culprits for now.
Thanks for your help here, and particularly for the information that
-frepo is an option/technique on its way out.
