Hi, Really good job David !! This error has already caused too much problem but that's all now ! And this is probably the same thing in the GateToLMF class because some similar problem has already occurred and perhaps in other output classes. Thanks again.

This is due to transient string object created within a function and returned with no copy... so, to solve the problem, one just have to replace, in include/GateToRoot.hh  the line  <tt> const char* GetFilePath()                  { return (m_fileName+".root").c_str();};</tt> by <tt>  const char* GetFilePath()                  { static char fp[512]; strncpy(fp,(m_fileName+".root").c_str(),511); return fp;};</tt> and recompile, and all will be ok... (in the first version, (m_filename+".root") is a new transiant object, deleted at the end of the function, so its "c_str() member will not be valid outside of the function itsef...) Thanks to all,     cheers Simon Stute a écrit : <blockquote type="cite"><div>Hi all, I remember I already had this problem on Suse10.2 and Ubuntu Dapper 6.0.6, but it appeared only few times and then it disappeared ...
