    <p>I have 32bit MinGW and 64 bit Eclipse CDT installed on 64 bit Windows 7 with an Intel <code>Core i7-3612QM</code>.

    1. COCan we see what the command(s) to compile/link are and what `gcc -v` says? Also, does it behave the same if you compile/link/run from the command line instead of from within Eclipse?

    2. CO@MichaelBurr Added `g++ -v` compiler output; exes still have the same problems.

    3. COWhere did you get the MinGW installation? I wonder if something is 'off' with the libstdc++.dll. Maybe a reinstall of MinGW might be in order. I've had great experience with the TDM distributions (http://tdm-gcc.tdragon.net/) or nuwen's MinGW (http://nuwen.net/mingw.html)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
