It gets into an infinite memory eating loop for me with 2.95.3 20010315 (SuSE). However, here's some more fodder for bug fixers: with 3.4, the loop is these functions, apparently calling each other in infinite ways (I just killed cc1plus at an arbitrary point, so your stack trace will look differently; at this time, gdb showed me the first ~9000 stack frames, before I had to kill it...) #0 0x08138b87 in break_out_target_exprs (t=0x4015dae0) at cp/tree.c:1509 #1 0x080548b7 in convert_default_arg (type=0x40199288, arg=0x0, fn=0x40199dec, parmnum=1) at cp/call.c:4416 #2 0x08054eaf in build_over_call (cand=0x446bf70c, flags=3) at cp/call.c:4577 #3 0x0805416d in convert_like_real (convs=0x40199dec, expr=0x4015dae0, fn=0x0, argnum=0, inner=-1) at cp/call.c:4149 #4 0x08053dca in convert_like_real (convs=0x446c1654, expr=0x4015dae0, fn=0x0, argnum=0, inner=0) at cp/call.c:4220 #5 0x0805a321 in initialize_reference (type=0x40199288, expr=0x4015dae0, decl=0x0) at cp/call.c:6132 #6 0x08113f48 in convert_for_initialization (exp=0x40199288, type=0x0, rhs=0x4015dae0, flags=3, errtype=0x84a0e78 "default argument", fndecl=0x40199dec, parmnum=1) at cp/typeck.c:6202 #7 0x080548fc in convert_default_arg (type=0x40199288, arg=0x0, fn=0x40199dec, parmnum=1) at cp/call.c:4430 #8 0x08054eaf in build_over_call (cand=0x446bf6b4, flags=3) at cp/call.c:4577 #9 0x0805416d in convert_like_real (convs=0x40199dec, expr=0x4015dae0, fn=0x0, argnum=0, inner=-1) at cp/call.c:4149 #10 0x08053dca in convert_like_real (convs=0x446c1528, expr=0x4015dae0, fn=0x0, argnum=0, inner=0) at cp/call.c:4220 #11 0x0805a321 in initialize_reference (type=0x40199288, expr=0x4015dae0, decl=0x0) at cp/call.c:6132 #12 0x08113f48 in convert_for_initialization (exp=0x40199288, type=0x0, rhs=0x4015dae0, flags=3, errtype=0x84a0e78 "default argument", fndecl=0x40199dec, parmnum=1) at cp/typeck.c:6202 #13 0x080548fc in convert_default_arg (type=0x40199288, arg=0x0, fn=0x40199dec, parmnum=1) at cp/call.c:4430 #14 0x08054eaf in build_over_call (cand=0x446bf65c, flags=3) at cp/call.c:4577 #15 0x0805416d in convert_like_real (convs=0x40199dec, expr=0x4015dae0, fn=0x0, argnum=0, inner=-1) at cp/call.c:4149 #16 0x08053dca in convert_like_real (convs=0x446c13fc, expr=0x4015dae0, fn=0x0, argnum=0, inner=0) at cp/call.c:4220 #17 0x0805a321 in initialize_reference (type=0x40199288, expr=0x4015dae0, decl=0x0) at cp/call.c:6132 #18 0x08113f48 in convert_for_initialization (exp=0x40199288, type=0x0, rhs=0x4015dae0, flags=3, errtype=0x84a0e78 "default argument", fndecl=0x40199dec, parmnum=1) at cp/typeck.c:6202 #19 0x080548fc in convert_default_arg (type=0x40199288, arg=0x0, fn=0x40199dec, parmnum=1) at cp/call.c:4430 #20 0x08054eaf in build_over_call (cand=0x446bf604, flags=3) at cp/call.c:4577 #21 0x0805416d in convert_like_real (convs=0x40199dec, expr=0x4015dae0, fn=0x0, argnum=0, inner=-1) at cp/call.c:4149 #22 0x08053dca in convert_like_real (convs=0x446c12d0, expr=0x4015dae0, fn=0x0, argnum=0, inner=0) at cp/call.c:4220 #23 0x0805a321 in initialize_reference (type=0x40199288, expr=0x4015dae0, decl=0x0) at cp/call.c:6132 #24 0x08113f48 in convert_for_initialization (exp=0x40199288, type=0x0, rhs=0x4015dae0, flags=3, errtype=0x84a0e78 "default argument", fndecl=0x40199dec, parmnum=1) at cp/typeck.c:6202 #25 0x080548fc in convert_default_arg (type=0x40199288, arg=0x0, fn=0x40199dec, parmnum=1) at cp/call.c:4430 W. ------------------------------------------------------------------------- Wolfgang Bangerth email: bangerth@ices.utexas.edu www: http://www.ices.utexas.edu/~bangerth/
