I recommend the lead developers of DMD to look into activating
more warnings in the dmd/src/posix.mak.
GCC 4.8.2 and especially Clang 3.4, both prepackage on Ubuntu
13.10/14.04 give a *lot* of warnings that seems to indicate
potential bugs in the DMD source code.
This setting gives useful warnings and at the same time avoid
the annoying ones
WARNINGS=-Wall -Wextra -Wno-deprecated -Wstrict-aliasing
-Wno-unused-parameter -Wno-unused-variable -Wunused-function
-Wno-unused-label -Wno-unknown-pragmas -Wno-sign-compare
-Wno-overloaded-virtual -Wno-missing-braces
-Wno-missing-field-initializers -Wno-logical-op-parentheses
For example there a *lot* of -Wsometimes-uninitialized which
IMHO seems like the most dangereous ones. This one is however
Clang specific but I have not had any problems running a Clang
compiled version of DMD. Further Clang compiles DMD about
twices as fast as GCC. Good work developers on disabling use of
STL in DMD!
I can do a pull request if desired for the posix.make update if
wanted.
Could be great too if someone run a static analyzer like on dmd
code http://www.cppcat.com I'll try when I back to Windows
