Bug #: 51035
Summary: GNAT bug detected error reported when compiling Ada
code
Classification: Unclassified
Product: gcc

The source code
When compiling a test program written in Ada using 4.6.1 20110908 (Red Hat
4.6.1-9) (i686-redhat-linux-gnu) (package gcc-gnat-4.6.1-9.fc15.i686), I see
the following error message:
[aravind@localhost ada]$ gnatmake test.adb
gcc -c test.adb
+===GNAT BUG DETECTED==+
| 4.6.1 20110908 (Red Hat 4.6.1-9) (i686-redhat-linux-gnu) Assert_Failure
sinfo.adb:2547|
| Error detected at test.adb:5:4 |
| Please submit a bug report; see http://gcc.gnu.org/bugs.html.|
| Use a subject line meaningful to you and us to track the bug.|
| Include the entire contents of this bug box in the report. |
| Include the exact gcc or gnatmake command that you entered. |
| Also include sources listed below in gnatchop format |
| (concatenated together with no headers between files). |
+==+
Please include these source files with error report
Note that list may not be accurate in some cases,
so please double check that the problem can still
be reproduced with the set of files listed.
Consider also -gnatd.n switch (see debug.adb).
test.adb
test.adb:5:39: extra ")" ignored
compilation abandoned
gnatmake: "test.adb" compilation error

The ada program text consists of the following lines:
--begin program
with Ada.Text_IO;
procedure Test is
subtype X is Integer range (1 .. 25);
Y: Integer range X'First .. X'Last := X'First;
begin
Ada.Text_IO.Put("Hello World");
end Test;
-- end program
The error lies with the line which reads:
subtype X is Integer range (1 .. 25);
The brackets around the 1 .. 25 are wrong. Once removed, the error goes away.
However, the compiler should report a nice error message and not report that a
bug in the compiler has been found.

here is the "gcc -v" output:
[aravind@localhost ada]$ gcc -v

expected behavior:
Just a compiler error due to syntax error
actual behavior:
A bug box even that is only a syntax error

[Bug c/51894] New: Fail to warn on likely precedence error in conditional
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=51894
Bug #: 51894
Summary: Fail to warn on likely precedence error in conditional
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: c

example program showing the failure to warn
example program showing the failure to warn:
gcc version 4.7.0
If you have:
if (ret = return_neg_one() == 1)
printf("direct_test==true\n");
else
printf("direct_test==false\n");
The compiler will warn:
/tmp/tmp.c:51:2: warning: suggest parentheses around assignment used as truth
value
But if it is a complex conditional:
if (!cond ||
(ret = return_neg_one() == 1))
The compiler will not warn. It seems it should warn in this case as well.
