Thomas Jarosch 2bcd675653 Verbose AST dump: Show if token is expanded from macro
I also added the token variable id, but that decreased
readability of the AST tree too much.

Thomas Jarosch 10fffbfce0 Use unsigned int for all flags
Frank Zingsheim reported: With the parameter 'flag_'
and the member variable '_flags' having the type 'int'
produces a lot of warings in clang:

"warning: implicit conversion changes signedness: 'int' to 'unsigned int'".

Thomas Jarosch e6f042dadc Multi process check: Sanitize error messages for illegal characters
before sending them across the pipe.

The deserializer died while deserializing
a string containing a binary zero.

Thomas Jarosch 36bcefc39d Don't crash when the deserialization of an error message fails
Found while scanning the code of an
open source project related to onions.

Robert Reif 193645318b Tokenizer: Remove macro in class declaration like 'class DLLEXPORT Fred {}' to be able to handle the class better later 2015-01-17 07:42:49 +01:00
Thomas Jarosch 08985bf68a Throw exception in getVariableFromVarId() if called with out_of_range varId
That way we have a chance to catch code bugs at all.

Thomas Jarosch 1cc85bfce3 Add bounds check to getVariableFromVarId()
While poking around the memory leak check,
I managed to trigger an out-of-bounds access
in the symbol database.

Fix it by sanity checking the variable id
passed to getVariableFromVarId().

Thomas Jarosch ef7f104335 Make sure we have a valid Variable pointer before dereferencing it
All other call sites check the pointer already.

Thomas Jarosch 059f9d056c Move to global variables to file scope
Putting them in the anonymous namespace
is the same effect as making them "static".

Thomas Jarosch 374af15bd4 Fix parsing linkage specifier from global function declaration
Our very own "tools/dmake.cpp" had a function declaration
featuring "static void foobar()" while the function implementation
did not have the 'static' keyword (which is perfectly legal code).
