Also indeed this bug is exactly related. http://sourceforge.net/tracker/?func=detail&aid=3535893&group_id=209965&atid=1011835 I have several questions: - What version do you use? Trunk or Stable? (If trunk, does it happens on stable as well?) - Do you compile libcppcms with ICU or without? - If it is built with ICU, what version? - What is the system locale? (output of locale) - What is the content header returned by the application (when it is not crashed) Now about libstdc++. - What version of GCC do you use, or you are using Clang? Please note: I ask about building CppCMS not your application. - How many cores does you computer has? - How do you link with libcppcms library statically or dynamically? I don't think it is related to threading library it may be a bug connected to facets, locking and standard library. > > >Em 07/08/2012, às 00:57, Artyom Beilis escreveu: > >See: >> >> >>1 0x0000000800939cb3 in cppcms::http::response::set_content_header (this=0x80ba7ac00, content_type=@0x7fffffffd590) at info.h:83 >> >> >>It looks like content_type you pass in info.h line 83 has very strange address 0x7fffffffd590 - i.e. it is very close to 0x7FFFFFFFF >>It seems strange to me check your code. >> >> >>Artyom Beilis >>-------------- >>CppCMS - C++ Web Framework: http://cppcms.com/ >>CppDB - C++ SQL Connectivity: http://cppcms.com/sql/cppdb/ >> >> >> >>>________________________________ >>> From: Vinicius Pavanelli <ds...@ha...> >>>To: cpp...@li... >>>Sent: Tuesday, August 7, 2012 5:15 AM >>>Subject: [Cppcms-users] Segmentation fault on FreeBSD in high load >>> >>>Hi, >>> >>>I'm new to CppCMS and been doing some work on it, too see where I get. >>>When I run the code on Linux/Gentoo it works fine, on FreeBSD it runs fine too, but on high loads it crashs (like when testing with siege). >>>Can anyone help me on what may be wrong with it?
