     <braunr> mcsim: if you find some good free static analyzer, let me know :)
     <pinotree> a simple one is cppcheck

+    <teythoon> whoa, llvm kinda works, enough to make scan-build work :)
+    <braunr> teythoon: what is scan-build ?
+    <teythoon> braunr: clangs static analyzer
+    <braunr> ok
+    <teythoon> I'm doing a full build of the hurd using it, I will post the
+      report once it is finished
+    <teythoon> this will help spot many problems
+    <teythoon> well, here are the scan-build reports I got so far:
+      https://teythoon.cryptobitch.de/qa/2013-10-17/scan-build/
+    <teythoon> I noticed it finds problems in mig generated code, so there are
+      probably lot's of duplictaes for those kind of problems
+    <pinotree> what's a... better one to look at?
+    <teythoon> it's also good at spotting error handling errors, and can spot
+      leaks sometimes
+    <teythoon> hm
+    <teythoon>

+    <braunr> that's minor, the device always exist
+    <braunr> but that's still ugly

+    <teythoon> this is the issue it finds in mig generated server stubs:
+      https://teythoon.cryptobitch.de/qa/2013-10-17/scan-build/report-iU3soc.html
+    <braunr> this one is #if TypeCheck1
+    <braunr> the libports one looks weird indeed
+    <teythoon> but TypeCheck is 1 (the tooltip shows macro expansion)
+    <teythoon> it is defined in line 23
+    <braunr> oh
+    <teythoon> hmmm... clang does not support nested functions, that will limit
+      its usefulness for us :/
+    <braunr> yes
+    <braunr> one more reason not to use them
