[Bug c++/38433] New: Incorrect handling of line termination character with trailing spaces

["eric dot niebler at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

In the attached file, there is a comment terminated with a line-termination
character (\) followed by spaces. This should NOT be considered a line
terminator, yet gcc considers it as such. From 2.1/2 in the C++03 standard:

"Each instance of a new-line character and an immediately preceding backslash
character is deleted, splicing physical source lines to form logical source
lines."

That is, only backslashes immediately followed by a newline are considered line
terminators. The existing behavior of gcc violates the standard and conflicts
with the behavior of other popular C++ compilers (EDG, MSVC).
