4.3BSD crash dump help needed

[Rahul Dhesi]

I'm having trouble analyzing a 4.3BSD crash dump.  Using adb on the
dump thus:

     adb -k vmunix.1 vmcore.1 << \EOF
     $c
     EOF

give this output:

     sbr f868 slr 3070
     p0br e00 p0lr 160 p1br 1600 p1lr ffde
     panic: Segmentation fault
     _boot()	from 8002694b
     _boot(0,0) from	_panic+3a
     _panic(8003ef90) from _trap+ac
     _trap()	from _Xtransflt+1d
     _Xtransflt(800691d8,1) from 8000b5e7
     _newproc(1) from _fork1+b3
     _fork1(1) from _vfork+b
     _vfork() from 80027265
     _syscall() from	_Xsyscall+c
     _Xsyscall(23c80,7fffe340,17948,0,7fffdd34,7fffdd30) from 3a03
     _Syssize(17934,23c80,7fffe340,17948) from 38ac
     _Syssize(17934,27a40) from 46f3
     _Syssize(17934,62) from	1026
     ?(4,7fffeb3c,7fffeb50) from 3d
     ?()

I have not found the Xtransflt symbol anywhere in the source or in any
of the C libraries.  What am I overlooking?  The crash dumps always
give a similar stack trace.  If only I could figure out what Xtransflt
is I might have a clue.

Any suggestions?
