Hi there, The call to ``change_address'' in ``sjlj_mark_call_sites'' can generate additional instructions in ``LEGITIMIZE_ADDRESS''. These instructions are appended at the end of the function, however the pseudo-register(s) they set may be used by the ``mem'' rtx, thus resulting in access of uninitialized memory/register. The attached patch makes sure instructions are emitted before emitting store to ``mem''. The patch is against gcc-3_0-branch. Regards, -velco
