I am not able to compile the current trunk for 32 bits on Mac OS High Sierra - some details below. (The 64 bit version compiles and runs fine.) Is this a specific issue with my setup, or something more general?

I am not able to compile the current trunk for 32 bits on Mac OS High Sierra - some details below. (The 64 bit version compiles and runs fine.) Is this a specific issue with my setup, or something more general?

Seems like a peephole optimisation that doesn't understand symbol differences:

# [3827] list.insertbefore(tai_comment.Create(strpnew('path: '+infile.path)), hp);
leal -288(%ebp),%eax
call Lfpc_ansistr_decr_ref$stub
movw $0,(%esp)
movl -1108(%ebp),%eax
movl 4(%eax),%ecx
movl -1060(%ebp),%edx

> leal _$$fpclocal$_ld66-Lj892+12(%edx),%eax > movl %eax,%edx

->

# [3827] list.insertbefore(tai_comment.Create(strpnew('path: '+infile.path)), hp);
leal -288(%ebp),%eax
call Lfpc_ansistr_decr_ref$stub
movw $0,(%esp)
movl -1108(%ebp),%eax
movl 4(%eax),%ecx
movl -1060(%ebp),%edx
# Peephole Optimization: LeaMov2Lea done
# Peephole Optimization: Lea2Add done

> addl $12,%edx

Fixed.

Magnificent. Quick work - I can confirm that it now builds for me, and my own applications run correctly.

Thanks.

Colin

Sorry for it being down to one of my optimisations again! Nobody's perfect, I guess. Thanks Jonas for fixing it.
