 I build dev8 with same config. I also have this problem. Lynx says 
'HTTP/1.1 200 OK' and hangs.

 strace'ing this process produces the same results (SIGSTOP,SIGSEGV).
 lrtace'ing too (the same message as shown above).

 The virtual image of the process doesn't grow, CPU usage does.
 
 here what 'ps -c -l -C lynx' says about it:
  F S   UID   PID  PPID   CLS PRI ADDR    SZ WCHAN  TTY          TIME CMD
000 R   500  4343   862     -  19    -  3403 -      ttyp5    00:01:23 lynx
 - ie process is running.

 It takes 80% of my CPU and 13Mb of RAM.

 I meant ltrace, but neither ltrace, nor strace give anything in our
situation.

  Seems you'd better build lynx without '--without-charsets' switch to
configure.
