Assignee: [email protected]
Summary: [PyUNO] freeze on calling methods of method node of
Basic (basprov::BasicMethodNodeImpl)
Severity: normal
Issue Type: DEFECT
Classification: Code
OS: All
Reporter: [email protected]
Hardware: All
Status: CONFIRMED
Version: AOO 3.4.0
Component: code
Product: scripting
When I try to list method names in Basic module using script provider which
can be taken from document model by css.script.provider.XScriptProviderSupplier
interface.
It seems this problem is based on NULL invocation kept by pyuno instance.
Here is the result from gdb, first line is the result of print(method_node):
pyuno object (com.sun.star.script.browse.XBrowseNode)0x-4f7d2bdc{,
supportedInterfaces={com.sun.star.script.browse.XBrowseNode,com.sun.star.script.XInvocation,com.sun.star.lang.XTypeProvider,com.sun.star.uno.XWeak,com.sun.star.beans.XPropertySet,com.sun.star.beans.XFastPropertySet,com.sun.star.beans.XMultiPropertySet}}
Program received signal SIGSEGV, Segmentation fault.
