I'm trying to track down a Firefox SEGV + password sync issue on the Firefox Bugzilla. I wanted to build the firefox package with some debug information to be able to get a stack trace of the SEGV, but I can't compile the official PKGBUILD.
When running makepkg, some C++ files are unable to compile with clang, complaining that standard C++ headers such as <new> and <type_traits> are missing, even though libc++ is installed.
I've tried in a clean 'pacstrap base-devel' too, same issue.
Am I missing some dependency? Something else I'm missing?
