I am getting segmentation violations from inside of boost::thread Running valgrind, I get the following:
==31129== Thread 2: ==31129== Jump to the invalid address stated on the next line ==31129== at 0xEC834853E5894855: ??? ==31129== by 0x4A4DDE1: boost::function0<void, std::allocator<boost::function_base> >::function0(boost::function0<void, std::allocator<boost::function_base> > const&) (function_template.hpp:527) ==31129== by 0x4A4CF21: thread_proxy (thread.cpp:106) ==31129== by 0x31A0D06136: start_thread (in /lib64/tls/libpthread-2.3.4.so) ==31129== by 0x31A04C7532: clone (in /lib64/tls/libc-2.3.4.so) ==31129== Address 0xEC834853E5894855 is not stack'd, malloc'd or (recently) free'd ==31129== ==31129== Process terminating with default action of signal 11 (SIGSEGV) ==31129== Bad permissions for mapped region at address 0xEC834853E5894855 ==31129== at 0xEC834853E5894855: ??? ==31129== by 0x4A4DDE1: boost::function0<void, std::allocator<boost::function_base> >::function0(boost::function0<void, std::allocator<boost::function_base> > const&) (function_template.hpp:527) ==31129== by 0x4A4CF21: thread_proxy (thread.cpp:106) ==31129== by 0x31A0D06136: start_thread (in /lib64/tls/libpthread-2.3.4.so) ==31129== by 0x31A04C7532: clone (in /lib64/tls/libc-2.3.4.so)
It seems that when the new thread is created. Totalview shows that the thread dies in function_template.hpp at the line:
f.vtable->manager(f.functor, this->functor, boost::detail::function::clone_functor_tag)
Any thoughts on what could be causing this? I am using boost_1_34_0. I don¹t know if this is relevant, but I have a thread adaptor class that looks like:
class ThreadAdaptor { public: ThreadAdaptor( ExpressionBase& expr ) : expr_(expr) {} ThreadAdaptor(const ThreadAdaptor& ta) : expr_(ta.expr_) {} ~ThreadAdaptor(){} void operator()(){ expr_.evaluate(); } private: ThreadAdaptor& operator=(const ThreadAdaptor&); // no assignment ExpressionBase& expr_; };
Thanks for any advice, James
