[Gm2] gm2-2010-11-02 arrayptr[34] woes

[john o goyo]

Using the build of 2010-11-02, I started investigating the failures  
of the test-cases gm2/pim/pass/arrayptr3.mod (with no compilation  
option) and gm2/pim/pass/arrayptr4.mod (with compilation options - 
Os).  Findings follow.

(1) arrayptr3.mod:

I first compiled and ran the resulting binary.

johng: 565 [tst-gm2]=> gm2 -c -g arrayptr3.mod
johng: 566 [tst-gm2]=> gm2  -g arrayptr3.mod
johng: 567 [tst-gm2]=> ./a.out
terminate called after throwing an instance of 'int'
Abort (core dumped)

Invoking gdb on the binary and core file did not help.  A back-trace  
command resulted in gdb terminating with a segmentation fault.  I  
tried gdb directly.

(2) arrayptr4.mod

Compilation with the command "gm2 -c -Os arrayptr4.mod" did not  
complete.  After watching it consume al the time on one of the  
processors for over one minute, I killed it.


Advice gratefully accepted.
