Segfault in YAML::convert<std::string>::decode #270

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?
1. Compile yaml_test.cpp
2. Run yaml_test with simple.yaml as a command line argument

What is the expected output? What do you see instead?
Expected: There should be no output from the program. Program should run and 
terminate without error.
See: Segmentation fault.

What version of the product are you using? On what operating system?
Ubuntu 14,04 64-bit
g++ 4.8.2
yaml-cpp 0.5.1 (prebuilt packages from apt-get repositories libyaml-cpp0.5 and 
libyaml-cpp-dev)

Please provide any additional information below.

Further information: Running this as a standalone program and compiling and 
running with
g++ yaml_test.cpp -lyaml-cpp -lboost_system -lboost_filesystem -o yaml_test
./yaml_test ./simple.yaml

seems to work without issues (removing the dependency on boost also result in 
no error). 

However, if I compile from within a catkin (a wrapper around the cmake build 
system) workspace I get the segfault. I will see if I can strip down my catkin 
workspace to a more minimal version and see if I can track down the error 
further.

I have no idea what has changed, but I am no longer able to reproduce this 
error at all.
