--- Comment #9 from Jonatan GOebel <jonatan.goebel at digitel dot com.br> 2012-04-19 15:14:27 UTC --- Hi. The problem actually happen when using -Os and -frename-registers. Also the source code may note help, because it randomly happens on different parts of the code depending on compiling flags and source code size. But always stuck after a "return" that never returns.
