Wx Test Failures with 2.9.4 on Strawberry Perl

The Wx module's tests are failing for me with wxWidgets 2.9.4 on Dwim
Perl (which is Strawberry Perl 5.14 bundled with some other stuff) on
Windows 7.

Any suggestions for fixing this (or the next step in debugging it)
gratefully received.

I built and installed wxWidgets 2.9.4 using the Alien::wxWidgets module,
and that all went fine. Then I set WXDIR and WXWIN, and compiling the Wx
module (version 0.9917) appears to go OK. But then some of the tests
fail -- full output pasted at the end. For each failing test program a
Windows error window pops up saying 'perl.exe has stopped working:
Windows is collecting more information about the problem'.

Running prove directly on the first .t file that files _mostly_ gives
this output (along with one of those perl.exe crash windows):

  >C:\Dwimperl\perl\bin\perl C:\Dwimperl\perl\bin\prove.bat -v t\03_event.t
  t\03_event.t ..
  1..17
  ok 1 - event succesfully received
  ok 2 - no object destroyed
  ok 3 - still no object destroyed
  Dubious, test returned 5 (wstat 1280, 0x500)
  Failed 14/17 subtests

    Parse errors: Bad plan.  You planned 17 tests but ran 3.
  Files=1, Tests=3,  2 wallclock secs ( 0.09 usr +  0.17 sys =  0.27 CPU)
  Result: FAIL

However, on a few attempts it has successfully run all 17 tests and
given a PASS at the end -- even when run consecutively just by pressing
Up then Enter, a FAIL may be followed by a PASS or vice versa.

Doing exactly the same thing with wxWidgets 2.8.12 works fine, with all
tests passing. (I compiled both versions at once in different
directories, using local::lib to keep them separate, so am reasonably
confident I used the same commands with each.)

I only deviated from Wx's INSTALL.pod in using dmake (which seems to
come with Strawberry Perl) rather than nmake (which doesn't).

Here's the full test output:
