[Bug gdb/11316] New: response time of output command slows down from gdb 7.0.1 to gdb 7.0.50

["asmwarrior at gmail dot com" <sourceware-bugzilla at sourceware dot org>]

Hello.

I have use two version of gdb under Windows.

http://sourceforge.net/projects/mingw/files/GNU%20Source-Level%20Debugger/GDB-7.0.1/gdb-7.0.1-mingw32-bin.tar.gz/download
and
http://sourceforge.net/projects/mingw/files/GNU%20Source-Level%20Debugger/GDB-7.0.50.20100202/gdb-7.0.50.20100202-mingw32-bin.tar.gz/download

I have found that when I'm debugging a DLL file, in which, I would like to
output the wxString value. So, I use these command ( m_Buffer is a wxString)

output /c m_Buffer.m_pchData[0]@((wxStringData*)m_Buffer.m_pchData - 1)->nDataLength

GDB7.0.1 responses quite fast, but GDB7.0.50 has a noticeable time delay. Is
this a regression. In fact, we have several discussion here in the Codeblocks
forums:

By the way, I even build gdb7.0.90 current snapshot myself under Msys system,
but these time lag still exists. Can someone help me? 

Thanks.
