wxMac help: KERN_INVALID_ADDRESS at address: 0x42a40008 in wxListBase::GetCount (this=0x42a40000) at /netopt/ncbi_tools/wxMac-2.6.3/include/wx-2.6/wx/list.h:477

Hi
 
the this pointer looks suspicious (0x42a4000), as if it assumes a
outdated member variable layout somewhere. Try a clean rebuild of
everything.
 
Best,
 
Stefan

	Hello.

	 

	I have an app that reads xml files using an in-house tool and
views cached data with wxWidget. It run fine on wxWidget/wxMac 6.3.0
fine before.  Recently I made some change in the source codes on reading
data , compiling is fine but the app crashed after a xml file have been
read and loaded. 

	 

	Below is error msg from cmd line gdb.
