--- Comment #2 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
The following test (from pr58334)
program foo
implicit none
character(len=16) :: a,b,c
a="XXX"
b="&
&XXX"
c="XXX &
& XXX"
write(0,*) 'a=',a,' b=',b,' c=',c
endprogram foo
shows the same behavior.
BTW what -dH is supposed to do (I did not find it in the manual)?

--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Though, looking at the implementation and documentation of -dH, it sounds like
it is intentional. -dH is supposed to stand for abort the compiler after
issuing an error. That is not an internal compiler error, but just abort
requested by the user. So NOTABUG IMHO.

> man gcc | grep -- -dH
-dH Produce a core dump whenever an error occurs.
(This refers to a *compiler error* - so I should only need/use it to report a
gcc bug.)
But this flag shouldn't "trigger" an error when there is none without it or am
I missing something here?

I don't have mpi installed, so it is hard to find out if you get an error or
not - your testcase is clearly not self-contained; I certainly do get an error
and correct abort after that.

Self contained test in comment 2.

--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
So supposedly gfc_error needs to for buffered_p case also save and temporarily
clear global_dc->abort_on_error. Maybe various other changes needed for that.
Wonder what is -dH good for, don't really see when it would be really useful.

--- Comment #8 from Melven.Roehrig-Zoellner at DLR dot de ---
Thanks for the quick replies and the discussion about the "not-so-usefulness"
of the -dH switch (at least for our project).
We most probably used this switch by mistake - you might possibly improve the
documentation by adding
"-dH Produce a core dump whenever a *compilation* error occurs."
to prevent further misunderstandings for people who don't read the full
paragraph.
