optimize='\-O'\,

It seems you still have the optimiser flags in.

I think (this is from memory\, but hopefully is correct) in your existing configured build directory your best bet is to

1: edit config.sh. Find the line optimize='-O' and change it to optimize='' 2: ./Configure -S to rebuild the Makefile and other files which depend on the settings in config.sh 3: rerun make.

Hopefully your compiler line will then be:

`sh cflags libperl.so toke.o` -KPIC toke.c CCCMD = /bin/cc -DPERL_CORE -c -I/usr/include -I/usr/ucbinclude -I/usr/local/include

(ie that -O at the end is gone)

You'll end up with a perl built with no optimisation\, which might be slower that you would like.

A better but more involved solution would be to see if your compiler's documentation gives any clues on which flags to use to tune its behaviour; either by turning off all Global CSE (which the compiler appears to be reporting is where it's hitting its limits) or by telling it exactly how large a buffer to allocate for Global CSE (so that it doesn't attempt to do what it's currently doing\, and allocate a buffer that exhausts memory)

I have no idea how to do that\, but believe that some compilers let you do this sort of thing.

From @jhi

An alternative to this is to turn off the optimization only on the toke.c. rm config.sh and re-Configure with an additional parameter:

./Configure -de -Dtoke_cflags='optimize=""' ...

This should remove optimization from only the toke.c

Yes\, many compilers have an option like that\, -Olimit N or -Omaxmem=N or something of the sort.

Normally\, this is a good idea\, but for NCR MP-RAS you also need to turn off the optimizer for reg*.c\, or else regular expressions won't work. The first symptom of that will be a very puzzling failure to correctly build DynaLoader.

Your best bet here is to turn off the optimizer all around. See the section =item Optimizer in the INSTALL file for details.

Thanks for your suggestions anyway.
