Compiling the attached testcase with:
g++ fl_color.ii
gives:
fl_color.ii:12: error: conversion from `struct s*' to `enum e'
It should probably work, if I refactor it to:
unsigned long l = map[i][j].l;
x(&l);
it works.

------- Additional Comments From mmitchel at gcc dot gnu dot org 2004-01-16 17:23 -------
This problem occurs because extract_muldiv_1 calls "convert" to try to convert a
pointer to an enum.
As I've said before, almost *any* use of "convert" by the middle-end is a bug.
The middle-end simply cannot know what kinds of conversions the front-end might
or might not do.
The back-end should explicitly generate NOP_EXPRs or CONVERT_EXPRs if it wants
to do conversions.
