Re: phase 2 of wxWidgets 2.9 build

I've found more problems with wx 2.9. Specifically, I seem to be
having some problems with the table editor. Segfaults occur when I
edit columns of specific datatypes. I'm using the dellstore2 sample
database, available from http://pgfoundry.org/projects/dbsamples/.

The following datatypes segfault when I press return to commit changes:

SERIAL (though, curiously, not integer, even when it's our PK)
text/varchar(n)
date

The following do not:
integer
numeric

This occurs on the debug and release builds.

Here's a stacktrace from when I modify a varchar(50) field, country,
from dellstore2's customers table:

Program received signal SIGSEGV, Segmentation fault.

I also see errors like this, but only on the release build:

An error has occurred:

XRC error: memory:XRC_resource/xrcDialogs.cpp$frmHint.xrc:6: unknown
style flag "wxRESIZE_BOX"

An error has occurred:

XRC error: memory:XRC_resource/xrcDialogs.cpp$frmHint.xrc:6: unknown
style flag "wxTHICK_FRAME"


I've already removed all wxRESIZE_BOX and wxTHICK_FRAME flags, which
fixed lots of these errors on the debug build, so I've currently no
idea why this happens.
