https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63356 --- Comment #15 from fiesh at zefix dot tv --- Boost 1.58.0 has a workaround by making one function explicit. (https://github.com/boostorg/polygon/commit/634aa3de29d63dcf02a478ca2b5045c5e9ccb7e0) Since this means the bug becomes irrelevant for me, I suppose the number of people who do find the bug relevant has decreased to zero. ;)

In order to collect it, you have to provide a patch that is accepted into 4.9 and 5. You also need to be able to write a bill with explicit VAT (we are based in Germany). Alternatively, I'll donate the money to any charitable use of your choice, again subject to requiring a receipt from the charity receiving it.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63356 --- Comment #13 from fiesh at zefix dot tv --- Are there any news on this bug? At least for us, this keeps production code from being able to work with any boost 1.55, which is becoming an increasingly bigger issue.
