parseline() can call _XimParseStringFile() which can call parseline() which can call _XimParseStringFile() which can call parseline() .... eventually causing recursive stack overflow and crash. Limit is set to a include depth of 100 files, which should be enough for all known use cases, but could be adjusted later if necessary. Reported-by:

When trying to process file paths the tokens %H, %L, & %S are expanded to $HOME, the standard compose file path & the xlocaledir path. If enough of these tokens are repeated and values like $HOME are set to very large values, the calculation of the total string size required to hold the expanded path can overflow, resulting in allocating a smaller string than the amount of data we'll write to it. Simply restrict all of these values, and the total path size to PATH_MAX, because really, that's all you should need for a filename path. Reported-by:
