ah, probably hasn't been a problem because the alpha syscall table hasn't 
wired up this print handler in a long time :)

commit cc4b8f426a4ae9350cfe41b42b488b5d11836bd8

    Update syscall list for Linux/alpha

--- a/linux/alpha/syscallent.h
+++ b/linux/alpha/syscallent.h

-   { 3,    TS, sys_sigprocmask,    "sigprocmask"   }, /* 48 */
+   { 3,    TS, printargs,      "osf_sigprocmask"}, /* 48 */

and indeed, once i write a small test app that calls this syscall, strace 
segfaults when trying to trace it.  i'll poke around a little bit.
