[Bug c++/22551] [4.0/4.1 Regression] [ICE] in tree_low_cst, at tree.c:3843

["nathan at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org>]

------- Comment #12 from nathan at gcc dot gnu dot org  2005-10-17 08:36 -------
the overflow happens in the static constant assignment 'int b = 0x80000000'
assigns an unsigned long to an int, and overflows.  The int_cst as b's
DCL_INITIAL has the overflow flag set.  I rejected clearing the overflow flag
at that point, because I was worried about other overflow paths on the case
label expression (although I failed to excite any).
