>Description:
Beman Dawes reports:

I've just upgraded GCC from 3.2.1 to 3.2.3 for Win32 regression testing, and regex_timer had to be killed manually because it was looping.

Same results on a second machine.

John Maddock reports:

I have the same problem: it appears to be a bug in libg++ std::getline: the lines are being returned with a trailing \r on the end of each line - stripping all the \r's from the input text file used by that test fixes the issue.

[This is the Boost regex_timer regression test being discussed.]

State-Changed-Why:
    Hi. According to 21.3.7.9,10 getline(istream, string) uses
    '\n' as delimiter, whereas windows textfile are terminated
    by "\r\n". Therefore, it looks like regex_timer should
    use instead getline(istream, string, '\r') on windows
    platforms.
    Thoughts?
    Thanks,
    Paolo.
