[libmicrohttpd] libmicrohttpd trigger Segmentation fault

[hzm]

Hi,

  We use libmicrohttpd 0.9.14 (read from configure.ac) under linux/ARM
devices. A Segmentation fault was detected today for the first time.I
debugged the core file with gdb, and it showed as follow:

....
Program terminated with signal 11, Segmentation fault.

As it seems everything occured within libmicrohttpd, would it be a
problem from libmicrohttpd itself?
