[Bug bootstrap/13872] ICE during build

[pinskia at gcc dot gnu dot org]

------- Additional Comments From pinskia at gcc dot gnu dot org  2004-01-26 23:15 -------
This is a dup of bug 13584 (after some IRC debuging effect:
<tm2> it's even the same line of code...expr.c3873
<pinskia> can you do a "p debug_tree(from)"?
<tm2> I bailed out out of the debugger. hang on
<pinskia> ok
* dann (~dann@tracer.ics.uci.edu) has quit IRC (Quit: Leaving)
<tm2> (gdb) p debug_tree(from)
<tm2>  <call_expr 0x403a406c
<tm2>     type <void_type 0x4016be80 void type_6 VOID
<tm2>         align 8 symtab 0 alias set 169
<tm2>         pointer_to_this <pointer_type 0x4016bef4>>
<tm2>     side-effects
<tm2>     arg 0 <addr_expr 0x402e0c40
<tm2> ...
<tm2> looks very similar...it's a call_expr
<pinskia> does it have LTHUNK0 in it?
<tm2>        arg 0 <function_decl 0x401c6c3c *.LTHUNK0 type <method_type 0x410f91d0>
<pinskia> it is the same bug, ok
<pinskia> I will close it as a dup then
<tm2> ok
