BUT IF I CHECKOUT 1.7 VERSION FROM CODE.GOOGLE.COM AND I USE IT AFTER 
COMPILATION, I HAVEN'T OUT OF MEMORY PROBLEM:

What steps will NOT reproduce the problem?
1. checkout 1.7 version from code.google
2. change pom.xml of snakeyaml with version 1.8-snapshot
3. recompile snakeyaml
3. change pom.xml of my application to point to snakeyaml 1.8-snapshot
4. recompile my app
5. relaunch my app

THANKS IN ADVANCE

Do you mean you specified the 1.7 tag when you cloned the source ? Can you 
please attach the diff (hg diff)?

I did this steps:

1) hg clone https://snakeyaml.googlecode.com/hg/ snakeyaml (after clone in 
pom.xml the version is 1.8-SNAPSHOT)
2) launch mvn clean install
3) change my pom.xml:
<dependency>
<groupId>org.yaml</groupId>
<artifactId>snakeyaml</artifactId>
<version>1.8-SNAPSHOT</version>
</dependency>

4) relaunch my app
5) deserialize my large file with no problems

hg diff doesn't produce any text

if I change my pom.xml dependency:
<dependency>
<groupId>org.yaml</groupId>
<artifactId>snakeyaml</artifactId>
<version>1.7</version>
</dependency>

I have out of memory loading my large yml file 

Does the version 1.7 on http://repo2.maven.org/maven2/org/yaml/snakeyaml differ 
from I cloned from https://snakeyaml.googlecode.com/hg/

I don't known how I can help further so if you have any questions write well

Now it is clear. In the very first post you said:
1. checkout 1.7 version from code.google
while in fact it is not 1.7 version but the latest trunk. 
Here http://code.google.com/p/snakeyaml/wiki/changes you may see that issue 79 
(http://code.google.com/p/snakeyaml/issues/detail?id=79) has been fixed.

You may use the latest SNAPSHOT 
(http://code.google.com/p/snakeyaml/wiki/readme) or wait for the 1.8 release
