The problem isn't the GUI test. This is a problem in production code
when compiled and run on msw-xp with MinGW-w64 gcc. Demonstration:

/opt/lmi/bin[0]$./lmi_wx_shared --ash_nazg --data_path=/opt/lmi/data

File | New | Illustration
into "Specified amount" field, paste
  sevenpay 7; 250000 retirement; 100000 #10; 75000 @95; 50000
OK

Illustrated specified amount follows the input sequence, which is valid.
Now do this:

Illustration | Edit cell
click "..." button to the right of "Specified amount"

This appears on the console:
  pure virtual method called
and a messagebox pops up:
  Error

  Abnormal-termination handler called. Please report this problem.


Click OK in the messagebox, and this:
  In file ../include/wx/msw/private.h at line 809: 'UnregisterClass' \
  failed with error 0x00000584 (class still has open windows.).

appears on the console (quite appropriately, I suppose).

Apparently the complexity of this particular input sequence is not
the problem. Try this:

File | New | Illustration
click "..." button to the right of "Specified amount"
[test case for gdb below]

Same symptoms as above, even though that field contains "1000000".

The problem is not seen with "Death benefit option" (keyword only) or
"Extra policy fee" (numeric only). It is seen with "Payment", which,
like "Specified amount", accepts mixed keyword and numeric values.

Let's try the last example above in gdb:

/opt/lmi/bin[0]$gdb --quiet lmi_wx_shared.exe
