Specifically, it was noticed that certain function attribute 
checks are skipped if the function contains an asm block 
(https://issues.dlang.org/show_bug.cgi?id=12979), so attributes 
for asm blocks were added after the stable release:

https://github.com/D-Programming-Language/dmd/pull/4033

Obviously, the stable compiler doesn't recognize those subsequent 
changes in git HEAD, so you have to compile dmd from git source 
if you want to compile druntime from the latest git.
