Subject: [Bug ada/24880] New: (Ada) Conversion of user-defined integer type with Size fixed causes crashes
Date: Tue, 15 Nov 2005 19:55:00 -0000 [thread overview]
Message-ID: <bug-24880-10300@http.gcc.gnu.org/bugzilla/> (raw)
Explicit conversion from a numeric integer Type to Integer causes a crash of
gcc
when the type is defined with a Size representation clause.
The bug disappears if the representation clause is removed or
if the range begins with 0.
Environment:
System: Linux simone 2.6.12.051101 #1 Tue Nov 1 17:19:34 CET 2005 i686
GNU/Linux
Debian testing gnat-4.0 Version: 4.0.2-2
Architecture: i686
host: i486-pc-linux-gnu
build: i486-pc-linux-gnu
target: i486-pc-linux-gnu
configured with: ../src/configure -v
--enable-languages=c,c++,java,f95,objc,ada,treelang --prefix=/usr
--enable-shared --with-system-zlib --libexecdir=/usr/lib

--disable-werror --enable-checking=release i486-linux-gnu
How-To-Repeat:
---------------------------- File demo2.adb
procedure Demo2 is
S : constant := Integer'Size;
type Regoff_T is range -1 .. 2 ** (S-1);
for Regoff_T'Size use S;
B : Integer;
C : Regoff_T;
begin
B := Integer (C);
end Demo2;
--------------------------------------------- The crash message
~ gnatmake demo2
gcc-4.0 -c demo2.adb
gcc-4.0: Internal error: Erreur de segmentation (program gnat1)
Please submit a full bug report.

gnatmake: "demo2.adb" compilation error
-------------------------------- with gnat version 3.4
~ gnatmake demo2
gcc-3.4 -c demo2.adb
demo2.adb:6:04: warning: "C" is never assigned a value
gnatbind -x demo2.ali
gnatlink demo2.ali
