[Bug c++/14803] [3.4/3.5 regression] Spurious warnings on conversion of pointers to member functions


------- Additional Comments From pinskia at gcc dot gnu dot org  2004-04-01 02:04 -------
For some reason the expression has an overflow:
<integer_cst 0x401360a0 type <integer_type 0x400505e8 int> constant static overflow -4>
At typeck.c:5497 (in build_ptrmemfunc, at the assert)
n is <nop_expr 0x417dc5c0
    type <integer_type 0x417108b8 int SI
        size <integer_cst 0x4170e360 constant invariant 32>
        unit size <integer_cst 0x4170e400 constant invariant 4>
        align 32 symtab 0 alias set -1 precision 32 min <integer_cst 0x4170e3c0 -2147483648> max 
<integer_cst 0x4170e3e0 2147483647>
        pointer_to_this <pointer_type 0x4171d7c0>>
    constant invariant
    arg 0 <integer_cst 0x41790780 type <integer_type 0x4171d174> constant invariant -4>>
and delta is:
<nop_expr 0x417dc5e0
    type <integer_type 0x417108b8 int SI
        size <integer_cst 0x4170e360 constant invariant 32>
        unit size <integer_cst 0x4170e400 constant invariant 4>
        align 32 symtab 0 alias set -1 precision 32 min <integer_cst 0x4170e3c0 -2147483648> max 
<integer_cst 0x4170e3e0 2147483647>
        pointer_to_this <pointer_type 0x4171d7c0>>
    constant invariant
    arg 0 <integer_cst 0x4170ea80 type <integer_type 0x4171d000 long unsigned int> constant 
invariant 0>>
So when they are added together it sets the overflow bit for some reason (maybe setting the overflow 
bit to 0 will work).
