Enabling tracing with SIP, I get the following when I call the
clone() member function in C++...
FunctionBase * sipFunctionBase::clone() const (this=0x083b0878)
python.clone
sipFunctionBase::sipFunctionBase(const FunctionBase&) (this=0x0842b2d8)
python.copy
sipFunctionBase::~sipFunctionBase() (this=0x0842b2d8)
Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 1075068096 (LWP 12449)]
0x41abf5d8 in FunctionProjector::initializeFunction (this=0x8403940,
projector=0xbfffe4f0)
at ../../hippodraw/projectors/FunctionProjector.cxx:135
Current language: auto; currently c++
(gdb)
The Python code looks like ...
from sihippo import FunctionBase
class Linear ( FunctionBase ) :
def __init__ ( self, other = None ) :
if other :
FunctionBase.__init__( self, other )
print "python.copy"
self.initialize ()
else:
FunctionBase.__init__( self )
print "python.default"
self.initialize ()
def clone ( self ) :
print "python.clone"
return Linear ( self )
The segmenetation fault above occurs when I try to use the cloned
function from C++. It appears that SIP is destroying the clone
function when returning from the clone member function implemented in
Python.
What might I try next?
