We have a user here who is having trouble with an Ada program. The program
seems to go into an infinite loop in package initialization. The debugger
shows repeated calls to the CHMK ^i35 instruction.
Is there any way to find what system service a CHMK ^i35 is calling?
Has anyone had a similar problem with Ada? Any helps/hints/suggestions
would be much appreciated.

Using DEBUG, I found the CHMK #35 (hex 23) instruction at 7FFEDF8A.
The entry point for this system service vector should then be at -2
relative to this (7FFEDF88). Looking in SYS$SYSTEM:SYS.MAP, I found
that this is the vector for SYS$HIBER.
