Re: [Cppcms-users] Segmentation fault on FreeBSD in high load

[Artyom B. <art...@ya...>]

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.
