[Bug ada/29112] New: misleading error message for declarations in the wrong place
When a user tries to declare items e.g. at the start of the handled_sequence_of_statements of an accept_statment, the compiler issues an error message. But it seems to be the default Junk_Declaration message, which seems kind of wrong in the following situations: procedure errmsg is task T is entry foo; end T; task body T is begin accept foo do item: INTEGER; -- not allowed, ok begin -- notice the occurence of "begin" null; end; end foo; end T; begin null; end errmsg; The message is 9. accept foo do 10. item: INTEGER; | >>> declarations must come before "begin" 11. begin The declaration does in fact come before "begin". The same message here: procedure errmsg2 is begin x: INTEGER; begin null; end; end; To reproduce, run gnatmake on the units. I though that maybe a rewording might do, something like "declaration not allowed in HANDLED_SEQUENCE_OF_STATEMENTS" or "declaration must be in DECLARATIVE_PART" -- Summary: misleading error message for declarations in the wrong place Product: gcc Version: 4.2.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: ada AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: bauhaus at futureapps dot de GCC build triplet: i686-pc-linux-gnu GCC host triplet: i686-pc-linux-gnu GCC target triplet: i686-pc-linux-gnu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29112

[Bug middle-end/29109] bad code produced when compiling qt-3.3.6
--- Comment #5 from pinskia at gcc dot gnu dot org 2006-09-16 21:13 --- (In reply to comment #3) > I will not give an isolated test case, but the information on > http://bugs.gentoo.org/show_bug.cgi?id=133301 may even help more. SSP is not part of GCC until 4.x so we really cannot support that. And it was rewritten to be better anyways. So this is not a bug. -- pinskia at gcc dot gnu dot org changed: What|Removed |Added Status|UNCONFIRMED |RESOLVED Resolution||INVALID http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29109

Actually, it seems that the conditional on Wconversion was added before, at
revision 100541 by mmitchel (Notice the warn_conversion flag below).
