coredump from IMPLEMENT_APP(MyApp) on Mac OS

[Xu, Ming (NIH/NLM/NCBI) [F]]

It is built OK, the app is a parser of a proteomics search engine
output.
It has also a child frame dialog wrapping search engine. The parser
worked fine, I made some changes and the changes worked fine on Win32
and wxGTK. 
When the app only parses a search engine result file, it works fine;
when I
Use the frame dialog of the search engine to run search alone, it also
works fine. But when the search result (cached in memory) is loaded into
the parser and saved into a file, I got the error.

Hi Ming,

Are you sure you have built the library and your application correctly? 
Does the minimal sample work for you?
