error: modified (page-) pointer

[Stephane Russell]

Does anybody knows what this error means?

*** in free(): error: modified (page-) pointer

It seems to appear sometimes. In my case, it does while I try to compile 
pgadmin3 with wxWidgets. I also get it with the samples program of 
wxWidgets. I then tried to compile wxWidgets myself without thread 
support and the error is still there.

Thanks.
