https://svn.boost.org/trac10/ticket/12017 <p> Hi, </p> <p> I'm using Boost 1.60.0_1 (installed from Brew) and am trying to compile the following file: </p> <pre class="wiki">//mytest.cpp: #include &lt;boost/program_options.hpp&gt; #include &lt;string&gt; namespace po = boost::program_options; int main(int argc, char *argv[]) { po::variables_map vm; po::options_description desc; desc.add_options() ("test,t", po::value&lt;std::string&gt;()-&gt;default_value("something")) ; po::store(po::parse_command_line(argc, argv, desc), vm); po::notify(vm); return 0; } </pre><p> I'm using CMake to compile. When compiling in Release mode, everything works fine. But when compiling in Debug mode, i get a segfault in the store() function when I run the program without the -t option: </p> <pre class="wiki">(lldb) bt * thread #1: tid = 0x5f2ad5, 0x000000010001b9c3 mytest`boost::program_options::value_semantic_codecvt_helper&lt;char&gt;::parse(boost::any&amp;, std::__1::vector&lt;std::__1::basic_string&lt;char, std::__1::char_traits&lt;char&gt;, std::__1::allocator&lt;char&gt; &gt;, std::__1::allocator&lt;std::__1::basic_string&lt;char, std::__1::char_traits&lt;char&gt;, std::__1::allocator&lt;char&gt; &gt; &gt; &gt; const&amp;, bool) const [inlined] std::__1::vector&lt;std::__1::basic_string&lt;char, std::__1::char_traits&lt;char&gt;, std::__1::allocator&lt;char&gt; &gt;, std::__1::allocator&lt;std::__1::basic_string&lt;char, std::__1::char_traits&lt;char&gt;, std::__1::allocator&lt;char&gt; &gt; &gt; &gt;::size(this=0xffffffffffffffd5 size=0) const at vector:653, queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS (code=1, address=0xffffffffffffffd5) * frame #0: 0x000000010001b9c3 mytest`boost::program_options::value_semantic_codecvt_helper&lt;char&gt;::parse(boost::any&amp;, std::__1::vector&lt;std::__1::basic_string&lt;char, std::__1::char_traits&lt;char&gt;, std::__1::allocator&lt;char&gt; &gt;, std::__1::allocator&lt;std::__1::basic_string&lt;char, std::__1::char_traits&lt;char&gt;, std::__1::allocator&lt;char&gt; &gt; &gt; &gt; const&amp;, bool) const [inlined] std::__1::vector&lt;std::__1::basic_string&lt;char, std::__1::char_traits&lt;char&gt;, std::__1::allocator&lt;char&gt; &gt;, std::__1::allocator&lt;std::__1::basic_string&lt;char, std::__1::char_traits&lt;char&gt;, std::__1::allocator&lt;char&gt; &gt; &gt; &gt;::size(this=0xffffffffffffffd5 size=0) const at vector:653 frame #1: 0x000000010001b9c3 mytest`boost::program_options::value_semantic_codecvt_helper&lt;char&gt;::parse(this=0x0000000100103740, value_store=0x00007fff5fbff408, new_tokens=size=0, utf8=&lt;unavailable&gt;) const + 51 at value_semantic.cpp:45 frame #2: 0x000000010001934d mytest`boost::program_options::store(options=0x00007fff5fbff5c8, xm=0x00007fff5fbff6c8, utf8=&lt;unavailable&gt;) + 1207 at variables_map.cpp:125 frame #3: 0x0000000100000cad mytest`main + 445 frame #4: 0x00007fff92a5e5ad libdyld.dylib`start + 1 </pre><p> I noticed this happens only if the binary is linked with the static debug libraries, i.e libboost_program_options-d.a and libboost_program_options-mt-d.a.
