Hi Nick
Yes its not reproducible with cvs binutils. I realised that after a while. Its
one of the local patches I apply
than this issue happens. This has been working.
I debugged gas a bit.
My patch calls make_relative_prefix() and if I apply my patch and disable
make_relative_prefix() call it
works ok too.
The problem seems to be that the check inside gas/dw2gencfi.c:769
dot_cfi_startproc() assumes that if
(frchain_now->frch_cfi_data != NULL)
frchain_now->frch_cfi_data is NULL when initialised
when I look into the gas/subsegs.c:110
where the frchain_now is allocated then there is obstack_alloc call and this
member is not set to NULL
explicitly.
So unless obstack_alloc returns a 0 initialised memory area the above check in
dot_cfi_startproc() is not
correct
