I have noticed that GHDL complains of an "internal compiler" error
whenever it fails to compile, for whatever reason, including syntax
errors. For example, using this sample code (with a syntax error, the
missing "is" in the entity declaration):
ibrary ieee;
use ieee.std_logic_1164.all;
entity xor_gate
port
(
a : in std_logic;
b : in std_logic;
o : out std_logic
);
end entity xor_gate;
architecture rtl of xor_gate is
begin
o <= a xor b;
end architecture rtl;
I get the following output from GHDL:
xor_gate.vhd:5:3: missing "is" after identifier
xor_gate.vhd:5:3: (found: port)
xor_gate.vhd:0: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.

ghdl: exec error
******************** GHDL Bug occured ****************************
Please report this bug on http://gna.org/projects/ghdl
GHDL release: GHDL 0.28dev (20080721) [Sokcho edition]
Compiled with GNAT Version: 4.3.2 20081007 (Red Hat 4.3.2-5)
In directory: /home/pladow/
Command line:
ghdl -a xor_gate.vhd
Exception STORAGE_ERROR raised
Exception information:
Exception name: STORAGE_ERROR
Message: stack overflow (or erroneous memory access)
Call stack traceback locations:
0x80fe74b
******************************************************************
There have been no side effects, including no core file (I did a
'ulimit -c unlimited' before running). It hasn't been an issue, but
is a curiosity.
Thanks,
Pete
