Hello, Dimitry. You wrote 22 =D1=84=D0=B5=D0=B2=D1=80=D0=B0=D0=BB=D1=8F 2013 =D0=B3., 20:14= :50: DA> As Joerg Sonnenberger mentioned to me, the address 0x10351d6 you show in DA> the gdb session seems to be quite high, possibly pointing to some shared DA> library. Maybe you can try to figure out which library it is? Ok, very simple "hello, world!" program crashes too! And I have debug symbols for it ;-) Program terminated with signal 4, Illegal instruction.

So, by default clang from r247144 still (or again?) has problems with long NOPs. --=20 // Black Lion AKA Lev Serebryakov <lev@FreeBSD.org>
