Hi,

It looks like you have problems with gcc. Two plugins which you gcc uses has 
problems with resolving some internal functions (C++):

 - structleak_plugin.so can't resolve _ZN8opt_pass14set_pass_paramEjb
 - randomize_layout_plugin.so cam't resolve _ZN8opt_pass14set_pass_paramEjb

Because of that GCC fails to run. It is not LKRG problem.

Best regards,
Adam
