[OpenAFS] Server segfaults in 1.4.2 on linux 2.4.31

[Marc Dionne]

Sounds a lot like the "LWP vs setjmp" bug.  What's your glibc version?

If you can rebuild from source, try defining "USE_UCONTEXT" in param.h an=
d
see if it helps.  It currently gets defined for glibc 2.4 and above, but
only for linux26.  src/config/param.i386_linux24.h probably needs this
additional bit found in src/config/param.i386_linux26.h:

#ifdef __GLIBC__
#if (__GLIBC__ > 2) || (__GLIBC__ =3D=3D 2 && __GLIBC_MINOR__ > 3)
#define USE_UCONTEXT
#endif
#endif
