Toolchain Issues
Tango is in many respects pushing D to its boundaries, and as such exposes issues with the surrounding tool chains. Typically these issues have a ticket in our ticketing system, but as the repair of them usually are outside of our control, they aren't a normal part of our release processes (although they will show up in the relevant milestones when fixed). Thus you will see a list of the known issues here, with links to the relevant bug reports for the toolchains themselves.
In addition to these, there are some workarounds in Tango for compiler bugs. These doesn't always have a ticket in Tango's Trac, but may be listed here with the corresponding bugzilla entry and information on the workaround. When the compiler bug is fixed, the Tango code with the workaround should be cleaned.
Issues listed here should always have a corresponding bugzilla (or other issue tracker used) entry for it too. If it cannot be shown that the issue in fact is a problem with the tool, it should be removed from this page.
