In an Ada system using heavilly generic packages and generic procedures
and functions, I ALWAYS end up when trying to compile the higher level
units with a crash of the DEC Ada compiler. The crash occurs in the
routine SI_INST_BODY_BODY at line 1125 of the Ada compiler (Micro-VAX 2
running VMS 4.7 in LAVC with ADA V1.4-33)

Performance Report (SPR)
I modified the Ada code : I reduced the level of genericity by removing
some intermediate levels. The program offers the same functions, but is not
as flexible and expandable as before. However it crashes again in the SAME
PLACE. I have completly restructured the code to try to compile it. And now
I still have the same problem : CRASH.
I am stuck here. Obviously I submited several SPRs, no answers yet. Does
that mean that there is a limit of depth of generic which can be used with
the DEC compiler ? Does anybody have met this bug ? Any information is
welcome.

I encountered something similar to this while trying to compile a 2300 block machine generated package. The compile would run for about 30 mins on uVAX2 an would die in a like fashion. It seemed that the compiler could not quite recover when the process virtual space was exhasted. Take a look at your account's 'paging file quota', the system's SYSGEN parameter VIRTUALPAGECNT, and the size of the PAGEFILE. ( I had to bump VIRTUALPAGECNT upto around 58,000 :-). This was DecAda v1.3 P.S. turning up VIRTUALPAGECNT may require more GBLSECTIONS since process pagetables will grow.

I tried your little generic example under the Verdix BSD4.3 Ada compiler, with "ada G_DISPLAY.a", and it compiled without complaint. Is that a sufficient test? Kent, the man from xanth.
