Building GHDL from the Sourceforge mercurial snapshot failed on my system.
I try to build the GCC backend for x86-64, using the gcc-4.9.2 sources under Debian 8.1. The ghdl binary itself builds fine, but the process fails later during compilation of the VHDL libraries. I get this error: ../../../../ghdl -a --GHDL1=./ghdl1 --ieee=none -O2 -g --std=93 -P../std --work=ieee ../../src/vital2000/memory_p.vhdl ******************** GHDL Bug occured **************************** Please report this bug on http://gna.org/projects/ghdl GHDL release: GHDL 0.33dev (20141104) [Dunoon edition] Compiled with GNAT Version: 4.9.2 In directory: /home/joris/projects/debian/ghdl/g/gcc/build/gcc/vhdl/lib/v93/ieee/ Command line: /home/joris/projects/debian/ghdl/g/gcc/build/gcc/./ghdl1 -O2 -g --std=93 -P../std --work=ieee -P../std/ -P/data/tmp/ghdl/lib/gcc/x86_64-linux-gnu/4.9/vhdl//v93/std/ -quiet -o memory_p.s ../../src/vital2000/memory_p.vhdl Exception CONSTRAINT_ERROR raised Exception information: Exception name: CONSTRAINT_ERROR Message: trans-rtis.adb:1633 range check failed Call stack traceback locations: 0x5d536a 0x5d5984 0x5d6985 0x5d9aeb 0x5d9f41 0x6298bd 0x5fd7d8 0x62ec55 0x58be77 0x5645fe 0x939450 0x93b08e 0x58bec9 0x561b75 0x7fd208feeb43 0x56201f 0xfffffffffffffffe ****************************************************************** Execution terminated by unhandled exception Exception name: CONSTRAINT_ERROR Message: trans-rtis.adb:1633 range check failed Call stack traceback locations: 0x5d536a 0x5d5984 0x5d6985 0x5d9aeb 0x5d9f41 0x6298bd 0x5fd7d8 0x62ec55 0x58be77 0x5645fe 0x939450 0x93b08e 0x58bec9 0x561b75 0x7fd208feeb43 0x56201f 0xfffffffffffffffe ../../../../ghdl: compilation error -- Joris.
