https://svn.boost.org/trac10/ticket/1587 <p> NOTE: boost::program_options has a serious bug, so it'll crash if the value part of a setting is missing. E.g. the below snippet at the end of my settings.ini file crashes if I uncomment the last line. </p> <hr /> <p> log_fname_info = info.log log_fname_problems = problems.log log_fname_status = status.log #log_fname_verbose = </p> <hr /> <p> I want to use a blank setting to mean "no verbose log file" in the above code. I've flagged it showstopper for this reason. </p> <p> It crashes on windows XP, in both debug and release versions, and normal and static link builds. Not tested on linux yet. </p> <p> Specifically, it seems to be happening in po.store(), and (on windows at least) it is caught as an 'other exception' in the below code. e.what() just outputs '!'. The exception is arising in kernel32.dll apparently. </p> <pre class="wiki">try{ po::store(po::parse_config_file(config_file,config_options), config_map); }catch(boost::program_options::invalid_option_value e){ std::cerr&lt;&lt;"invalid_option_value exception thrown parsing config file:"&lt;&lt;e.what()&lt;&lt;"\n"; return -2; }catch(std::exception e){ std::cerr&lt;&lt;"Other exception thrown parsing config file:"&lt;&lt;e.what()&lt;&lt;"\n!"; return -2; } </pre> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/1587 Trac 1.4.3 Douglas Gregor Fri, 16 May 2008 19:09:24 GMT https://svn.boost.org/trac10/ticket/1587#comment:1 https://svn.boost.org/trac10/ticket/1587#comment:1 <ul> <li><strong>description</strong> modified (<a href="/trac10/ticket/1587?action=diff&amp;version=1">diff</a>) </li> </ul> Ticket Vladimir Prus Sat, 17 May 2008 05:36:00 GMT https://svn.boost.org/trac10/ticket/1587#comment:2 https://svn.boost.org/trac10/ticket/1587#comment:2 <ul> <li><strong>severity</strong> <span class="trac-field-old">Showstopper</span> → <span class="trac-field-new">Problem</span> </li> </ul> <p> I cannot reproduce this crash on Linux.
