[cfe-dev] CFG and CXXDefaultInitExpr

[Enrico P]

Hello,

I'm doing some work on -Wuninitialized to make it detect the use of
uninitialized fields within C++ constructor bodies.

When the CFGBuilder visits a CXXDefaultInitExpr, it won't visit its
children because CXXDefaultInitExpr::children() returns an empty
child_range.

Is there any reason for this (maybe related to the comment at line 1108 of
CFG.cpp?), or is it safe to have it return a non-empty child_range?

Thanks,
Enrico
