Why am I getting a segmentation fault in Typheous when I perform a POST request?

It's really tricky in our production environment( Red Hat Enterprise Linux Server release 5.4 (Tikanga) and curl 7.15.5 (x86_64-redhat-linux-gnu) libcurl/7.15.5 OpenSSL/0.9.8b zlib/1.2.3 libidn/0.6.5) that the POST request become to GET request automatically. Below is the relative log provide by nginx.

cache: [GET /login] miss
url->http://localhost:8080/login

About to connect() to localhost port 8080

In fact, we send a POST request to login, but it convert to GET actually.

In our development environment( which is Ubuntu12.04 and curl 7.22.0 (x86_64-pc-linux-gnu) libcurl/7.22.0 OpenSSL/1.0.1 zlib/1.2.3.4 libidn/1.23 librtmp/2.3), everything goes ok.

Who can explain it?
