Hi,
i guess you spotted a bug in flext.
in C++ it's valid (although not common practice) to delete a NULL ptr
and flext doesn't handle that correctly.
As a quick fix, you can search flsupport.cpp for the following
function and insert one line of code as shown below.
void flext_root::operator delete(void *blk)
{
if(!blk) return; // INSERT THIS LINE
Then recompile and reinstall flext.
Please let me know if it helps.
I'd appreciate flext-related stuff to be sent to the flext mailing list.
thanks,
gr~~~
