[cfe-dev] sizeof (RopeRefCountString)

[Zhongxing Xu]

Hi,

In RewriteRope.cpp, RewriteRope::MakeRopeString(const char *Start, const
char *End),
we calculate the AllocSize by:

unsigned AllocSize = sizeof(RopeRefCountString) - 1 + AllocChunkSize;

I guess here the intention is: sizeof(RopeRefCountString) is 5. But gcc says
sizeof(RopeRefCountString) is 8. So the actual AllocSize is 4087. Should we
minus 4 instead of 1 to make the AllocSize 4084?
