This is a bug in the compiler. Report it to your distro.

@Bu11etmagnet how can be arch and ubuntu be broken at same time ? for reassurance , i will run build on fedora

Bu11etmagnet commented 5 years ago

@acnologia000 they can be broken at the same time if they use GCC versions which contain the same bug.

FirstLoveLife commented 5 years ago

you should post a thread on gcc's bugzilla

moneroexamples commented 5 years ago

It was already fixed on gcc 9.2

For other gcc, check here: https://github.com/ipkn/crow/issues/303

Using clang would be easiest fix.
