With a stock GCC 4.4.2 bootstrapped with the default options (-g -O2, I think)
on alpha the symptoms are the same. Here is a backtrace:
(gdb) run -vP2 -Pp
Starting program: /home/lbrenta/gcc-obj/gcc/gnatmake

The following project file is known to work on alpha-gnu-linux with GCC 4.3.4:
project Build_XMLAda is
for Source_Dirs use (dom, input_sources, sax, schema, unicode);
for Library_Name use xmlada;
for

I have access to an alpha-linux-gnu machine, please tell me if I can help
narrow this problem down.
A debug trace from gdb would be a nice starting point.

Even an empty project file triggers the bug:
$ cat p.gpr EOF
project p is
end p;
EOF
$ gdb gnatmake
(gdb) run -vP2 -Pp
Starting program: /usr/bin/gnatmake -vP2 -Pp
GPR_PROJECT_PATH=.:/usr/share/ada/adainclude/

Actually the disassembly above was that of Tab.Get_Next. The source for
Tab.Get_Next is:
function Get_Next (T : Instance) return Elmt_Ptr is
begin
if T = null or else not T.Iterator_Started
#1 0x02853dd8 in ?? () from /usr/lib/libgnatprj.so.4.4
#2 0x02856abc in prj__part__parse () from /usr/lib/libgnatprj.so.4.4
#3 0x0284df7c in prj__pars__parse () from /usr/lib/libgnatprj.so.4.4
Well, there's no such thing as libgnatprj.so in GCC sources/Makefiles.
