[omniORB] Corba::String_member

[evgeni.rojkov at durr.com]

... would suggest using CORBA-types for communication only doing specific conversions before / after CORBA call

Best regards,

Hi,
Solved my problem which was due to not initializing a XXX_var, which
then of course crashed in the assignment operator of the String_members.
Was late yesterday :-)
Thanks for all your replies,
Immanuel

Hi,

The CORBA C++ mapping is special and has a mix of manual/automatic
reference counting. Would recommend you to get the CORBA Programming
with C++ book and follow the mapping in detail, any mistake could lead
to a memory leak or crash, we always test with valgrind to try to detect
errors as early as possible.

The new IDL to C++11 language mapping maps a IDL string to std::string,
but that is not supported yet by omniORB, see
https://osportal.remedy.nl/projects/idl2cppx0 for more details about
this new mapping and available implementations.
