http://gcc.gnu.org/ml/gcc-patches/2006-08/msg00238.html causes the gcc to hang. Gdb backtrace looks like (gdb) bt #0 htab_find_slot_with_hash (htab=0x60000000002cce30, element=0x2000000005417b20, hash=30308, insert=NO_INSERT) at /net/gnu-13/export/gnu/src/gcc-next/gcc/libiberty/hashtab.c:635 #1 0x40000000008f8310 in delete_variable_part (set=0x600000000053c630, loc=0x2000000005779b80, decl=0x2000000005417b20, offset=0) at /net/gnu-13/export/gnu/src/gcc-next/gcc/gcc/var-tracking.c:2232 #2 0x40000000008f8b80 in var_regno_delete (set=0x600000000053c630, regno=<value optimized out>) at /net/gnu-13/export/gnu/src/gcc-next/gcc/gcc/var-tracking.c:916 #3 0x40000000008fb1c0 in vt_find_locations () at /net/gnu-13/export/gnu/src/gcc-next/gcc/gcc/var-tracking.c:1729 #4 0x40000000008fc210 in variable_tracking_main () at /net/gnu-13/export/gnu/src/gcc-next/gcc/gcc/var-tracking.c:2951 #5 0x4000000000788b80 in ia64_reorg () at /net/gnu-13/export/gnu/src/gcc-next/gcc/gcc/config/ia64/ia64.c:8549 #6 0x400000000090e330 in rest_of_handle_machine_reorg () at /net/gnu-13/export/gnu/src/gcc-next/gcc/gcc/reorg.c:3816 #7 0x400000000071b830 in execute_one_pass (pass=0x6000000000008d88) at /net/gnu-13/export/gnu/src/gcc-next/gcc/gcc/passes.c:864 #8 0x400000000071bbb0 in execute_pass_list (pass=0x6000000000008d88) at /net/gnu-13/export/gnu/src/gcc-next/gcc/gcc/passes.c:911 #9 0x400000000071bc00 in execute_pass_list (pass=0x60000000000076c0) at /net/gnu-13/export/gnu/src/gcc-next/gcc/gcc/passes.c:912 ---Type <return> to continue, or q <return> to quit--- #10 0x400000000071bc00 in execute_pass_list (pass=0x6000000000007678) at /net/gnu-13/export/gnu/src/gcc-next/gcc/gcc/passes.c:912 #11 0x400000000022e960 in tree_rest_of_compilation (fndecl=0x2000000004e7ddc0) at /net/gnu-13/export/gnu/src/gcc-next/gcc/gcc/tree-optimize.c:418 #12 0x40000000001342a0 in expand_body (fn=0x2000000004e7ddc0) at /net/gnu-13/export/gnu/src/gcc-next/gcc/gcc/cp/semantics.c:3072 #13 0x4000000000794a30 in cgraph_expand_function (node=0x2000000004f23e90) at /net/gnu-13/export/gnu/src/gcc-next/gcc/gcc/cgraphunit.c:1194 #14 0x40000000007967f0 in cgraph_optimize () at /net/gnu-13/export/gnu/src/gcc-next/gcc/gcc/cgraphunit.c:1259 #15 0x40000000000ac070 in cp_finish_file () at /net/gnu-13/export/gnu/src/gcc-next/gcc/gcc/cp/decl2.c:3341 #16 0x40000000000038a0 in finish_file () at /net/gnu-13/export/gnu/src/gcc-next/gcc/gcc/cp/cp-lang.c:144 #17 0x40000000001e8e00 in c_common_parse_file ( set_yydebug=<value optimized out>) at /net/gnu-13/export/gnu/src/gcc-next/gcc/gcc/c-opts.c:1165 #18 0x40000000006c6240 in toplev_main (argc=<value optimized out>, argv=<value optimized out>) at /net/gnu-13/export/gnu/src/gcc-next/gcc/gcc/toplev.c:999 #19 0x4000000000202c40 in main (argc=17, argv=0x60000fffffffb5a8) at /net/gnu-13/export/gnu/src/gcc-next/gcc/gcc/main.c:35 (gdb) -- hjl at lucon dot org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |aoliva at gcc dot gnu dot | |org Status|WAITING |NEW Ever Confirmed|0 |1 Last reconfirmed|0000-00-00 00:00:00 |2006-08-10 06:22:20 date| | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28672
