This weird exception keeps occuring and visual D is not bringing me to the place in my code that might be calling it.


Message:

First-chance exception: std.format.FormatException Unterminated format specifier: "%" at C:\D\dmd2\windows\bin\..\..\src\phobos\std\format.d(830)


I've gotten rid of it before, but I'm not sure how.

Here's the call stack:

The exception is not listed in the Exception Settings checkable list.   I will try commenting out the D source code that throws it.

The easiest solution is just to ignore the exception and continue.  The exception doesn't occur in release mode.
