Greetings,

I am attempting to parse a yaml file in some C code and have most recently tried to use:

yaml_emitter_set_output_string

However after compiling and running the program I receive an internal emitter error.

Files attached:

yaml_error.c mzagrabe.yaml

compiled with:

gcc -c yaml_error.c && gcc -lyaml -o yaml_error yaml_error.o

command line:

% ./yaml_error mzagrabe.yaml

libyaml version:

Debian Sid

ii libyaml-0-1 0.1.1-1 ii libyaml-dev 0.1.1-1

In the PARSER API Synopsis example program there is a memory bug.

the while loop checks the type of the event.type but the event has already been deleted. the delete invalidates the event type under debian on my x86 system. to fix the bug, i had to introduce another integer variable to hold the type so that the loop can check that to know when to end.
