I haven't modify any code of openssl. So I don't know why it aborted.

The version I used previously is 0.9.8a. So I tried to update it to the
latest version 0.9.8i. And it finally works fine. Maybe there are some
enhancement or bug fix in later release.
I also tried some release before i. And I found the problem was disapeared
from version 0.9.8f. I checked change log, and found following record.
*) Changes to avoid need for function casts in OpenSSL: some compilers
(gcc 4.2 and later) reject their use. [Kurt Roeckx <[EMAIL PROTECTED]>,
Peter Hartley <[EMAIL PROTECTED]>, Steve Henson]I don't know whether the
aborting was caused by that case.
BTW, the c library that I used was uClibc 0.9.27.
Anyway, thanks very much for your help.
