[wx-dev] some bugs in 2.8.0 on ms windows, using Borland C++ Builder 6/4

[lego]

Hi,

I have done some investigation in the problem I am having with the code.
Since the wxWidgets source is mainly in macros and I have a large program,
the simplest way was to create a hashmap in the program context. 

wxStringToStringHashMap m_headers;

When it is created, it has a NULL table and quite random (uninitalised?)
values, like buckets = 22276204... I have called its clear method 

 0059DB83 _wxHashTableBase2::DeleteNodes(buckets=193, table=????,
dtor=:00488FF8)

and that does 193 (not 22275204!) iterations through on the empty map, but
does not fail, however, when I call wxHTTP it used to fail at this point,
but now it started failing at iteration when accessing NULL table by index.
I have fixed it by substituting the hasmap with a list, but think that other
problems I have might be caused by this or something else that got my code
broken...

Cheers
