Build stock perl 5.5.640 on IRIX 6.5.6 ( MIPSpro 7.3 plus patchSG0003709 )

CFLAGS='-O3 -g3'

miniperl dies of a segment fault when build Dynaloader (pm_to_blib)
(stack trace below)

The situation is really strange ( it smells like a memory corruption
problem)

- It does build with -DDEBUGGING
- It does build when doing the failing

Here is a post mortem backtrace

NOTE, that the version information below comes from the successful build
with -DDEBUGGING.
The failing build process didn't have this option.

Are the results are unchanged with change#4970?
