Summary: [4.6 Regression] web.c:union_match_dups segmentation
fault for bfin
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: target
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: Stuart.Henderson@analog.com
bfin-uclinux fails to build libgfortran due to a seg fault in union_match_dups
in web.c
Looks like this is the blackfin version of:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43742
which was caused by:
http://gcc.gnu.org/viewcvs?view=revision&revision=158187
i'm not sure what the guilty pattern is though.
