[Bug c/52927] procps do not work with -Os flag.
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52927 --- 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.

And the program stuck, he probably returned to somewhere else.
