I have just find a noticeable time delay when I enter a command line. I'm debugging a DLL file under Windows, using 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 When I try to view the wxString value in a DLL, I entered this command to GDB output /c m_Str.m_pchData[0]@((wxStringData*)m_Str.m_pchData - 1)->nDataLength But it takes several seconds to give the answer returned from GDB. I built the latest snapshot of branch/gdb-weekly-7.0.90.20100223.tar.bz2 and current/gdb-7.1.50.20100223, but the delay still exists. In fact, this delay does *not* exist before, at least in the http://sourceforge.net/projects/mingw/files/GNU%20Source-Level%20Debugger/GDB-7.0.1/gdb-7.0.1-mingw32-bin.tar.gz/download, which is release in 20100107, In this version, the response from GDB is really fast. I have check the commit log from 20100107 to 20100202, I personally suspect there's regression in the CLI of handing command input c_expression. Also, I have create a bug report here : http://sourceware.org/bugzilla/show_bug.cgi?id=11316 Does anyone experience this time delay? Thanks
