------- Comment #4 from vmakarov at redhat dot com 2010-05-18 21:40 ------- Thanks for reporting the problem. The problem has no effect on generated code whatever initialization is used. The code in question tries to get basic block for BARRIER which is wrong. Whatever it gets basic block for BARRIER the code will still work right.
In any case, it is really annoying to see such valgrind diagnostic. Therefore I'll send a patch to fix it soon. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43332
