EXC_BAD_ACCESS in OscOutboundPacketStream.cpp #8

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Open a new Command line Tool project on XCode 4.7
2. Compile the oscpack library (ip and osc folders)
3. Run the SimpleSend.cpp program

What is the expected output? What do you see instead?
It should send an osc message to SimpleReceive.cpp (on another command line 
project). Build works well but when i do Run, there is a crash in 
OscOutboundPacketStream.cpp at line 191-192:

uint32 *previousElementSizePtr =
                (uint32*)(data_ + *reinterpret_cast<uint32*>(elementSizePtr_));

The problem is: Thread 1: EXC_BAD_ACCESS (code=13, address=0x0)

This crash happens also in OscOutboundPacketStream.cpp at line 324:

EndElement( messageCursor_ );

What version of the product are you using? On what operating system?
I'm using the latest version of oscpack (1.0.2) on Xcode 4.7 on Mac OSX Lion 
10.7.5

Please provide any additional information below.
The compilation of SimpleReceive.cpp works perfectly (Build & Run). No bugs.
Also, address=0x0 means 0 in hex so that should mean that the pointer is NULL 
or something... Thanks for your help.

Ok I resolved the issue by changing the scheme: 64 bit doesn't work, 32 bit 
does!

Hi Antoine, This problem should be fixed now. Would be able to please try the 
latest SVN head of oscpack in 64 bit mode?

Here are instructions for doing an SVN checkout:

Thanks,

Ross.

Note that I've added SimpleSend and SimpleReceive to the Makefile and they are 
building and running fine here (OSX 10.7, XCode 4.5.1)
