Well, it's quite a lot of files in different directories so I will only tar them
up if you realy want them

The compiler used is a cvs snapshot from this weekend. configuration used is:

../gcc/configure --prefix=/opt/ada --enable-libada --enable-shared 
--enable-languages=ada,c

The error only apears with the debug compile, not with release.

Thank you

Martin

------- Additional Comments From charlet at gcc dot gnu dot org  2004-03-08 22:44 -------
Yes, sources are needed to investigate such failures (or at the very
least a gdb session on gnat1 with a few appropriate prints).

This is a general dwarf2 bug, not an Ada bug, so recategorizing and
putting on hold waiting for the sources.

------- Additional Comments From shalla at darkover dot isilm dot com  2004-04-09 14:50 -------
I have a nearly identical dwarf2 bug in C/C++, and a trivial test case. Here:

///////////////////////////////////
int main() {
  double d = 1.0;
  char x[(int) d];
  return 0;
}
///////////////////////////////////

g++34 -g ice.bug.c
ice.bug.c: In function `int main()':
ice.bug.c:5: internal compiler error: in loc_descriptor_from_tree, at
dwarf2out.c:8863
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

Of course, if I leave the -g off, it compiles and executes properly.

I am using the prerelease snapshot of 3.4.0. on i686-pc-linux-gnu as well.

[pinskia at gcc dot gnu dot org]

------- Additional Comments From pinskia at gcc dot gnu dot org  2004-04-09 15:01 -------
Since I do not have an Ada compiler on any machine that has dwarf2 support could someone run in this 
in the debuger and see what the debug_tree(loc) prints out.

Also the shalla's testcase is filed under 149000.

Just to make it clear that the problem is not really fixed on the 3.4 branch,
merely swept under the rug.  An --enable-checking build will have 6 failures:
