 Yes, only in i386. My fault. Sorry.
 
 The libc in dfly/amd64 hasn't "getcontext", only
 lib/libc/i386/sys/getcontext.S. I think the team worked in the i386
 version of "getcontext" before of the creation of dfly/amd64 GSoC
 project, but they not ported all libc to amd64
 
 I've opened a bug in dfly bugtracker:
 http://bugs.dragonflybsd.org/issue2179
 
 References:
 - lib/libc/i386/sys/getcontext.S
 - Request for swapcontext and getcontext to be ported to our libc:

 - Port DragonFly to the AMD64 architecture:

 Tomorrow I'll review the problem and I'll give you a solution. The
 problem is only with amd64, so I think the better is import run-libmicro
 in pkgsrc because this is broke for all OS and create two Makefiles for
 DragonFly. I think the fix in libc is hard, so I'll disable temporary
 the code affected.
 
 Thanks.
