<DIV>Thanks. I have found that the debugger is usually an excellent resource for strange issues, but for this problem, the plot thickens...</DIV> <DIV> </DIV> <DIV>The stack trace indicates that the path object destructor ~path() is calling free(void * pBlock blah...) in free.c and that is when the break occurs due to the filesystem::error.</DIV> <DIV> </DIV> <DIV>What does that mean? It seems like there is nothing I can do if it is being caused by the destructor and/or Windows heap functions, but maybe I am not reading the output correctly.<BR><BR><B><I>goochrules! <goochrules@gmail.com></I></B> wrote:</DIV> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid">> - Upon hanging, I now get a message box: <BR>> Unhandled exception at 0x77e73887 in PICtool-w32.exe: Microsoft C++<BR>> exception: boost::filesystem::filesystem_error @ 0x0012f170. <BR><BR>You can really help your self by using the debugger on this one. In<BR>general, you want to break on when any exceptions of this type are not<BR>handled, and then use the stack trace to see all the various functions<BR>and bits of data that lead up to this problem.<BR><BR>Specifically (for VS.Net 2003) you want to click "Exceptions..." in<BR>the Debug menu. Then for "C++ Exceptions" make sure in the group "If<BR>the exception is not handled:" that "Break into hte debugger" is<BR>selected. You may want to also select this option for "When the<BR>exception is thrown", but be aware that this may give you more hits<BR>than then one you're looking for.<BR><BR>Then it is a matter of starting the debugger (F5 I believe, or<BR>Debug->Start) and using the watch and call stack windows to figure out<BR>what is causing the exception.<BR><BR><BR>Hope this helps.<BR><BR><BR>-- Matthew Peltzer<BR>-- goochrules@gmail.com<BR>_______________________________________________<BR>Boost-users mailing list<BR>Boost-users@lists.boost.org<BR>http://lists.boost.org/mailman/listinfo.cgi/boost-users<BR></BLOCKQUOTE><p> <hr size=1>Do you Yahoo!?<br> <a href="http://us.rd.yahoo.com/mail_us/taglines/50x/*http://promotions.yahoo.com/new_mail/static/efficiency.html">Yahoo!
