Your problem compiler was labeled a "pre-release" version. For major releases the gcc
team will continually strive for better code generation. This means tweaks to
optimizers. Shortcuts can be introduced which should have corner cases, so there is some
risk in using a pre-release compiler. This is true regardless what you are trying to
compile, i.e. it is not a function of "old boost" necessarily.
We cannot hold this against the gcc team, they warned you, in the version labeling.
On the other hand, one might question the arch linux folks, who bet on a horse before it
was mature enough to depend on. That seems like unnecessary risk to me.
