Bug #: 51624
Summary: [4.6/4.7 regression] Assert_Failure atree.adb:808 on
IRIX 6.5
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: ada
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: ro@gcc.gnu.org
CC: charlet@gcc.gnu.org, ebotcazou@gcc.gnu.org
Host: mips-sgi-irix6.5
Target: mips-sgi-irix6.5
Build: mips-sgi-irix6.5
Between 20111209 (r182157) and 20111216 (r182397), Ada bootstrap started to
fail
on IRIX 6.5 in stage 3:
+===========================GNAT BUG DETECTED==============================+
| 4.6.3 20111216 (prerelease) [gcc-4_6-branch revision 182397]
(mips-sgi-irix6.5) |
| Assert_Failure atree.adb:794 |
| Error detected at ali.adb:2008:45
When I apply the patch for PR bootstrap/50686 just suggested, I observe a
similar
ICE on mainline, too:
+===========================GNAT BUG DETECTED==============================+
| 4.7.0 20111216 (experimental) [trunk revision 182408] (mips-sgi-irix6.5) |
| Assert_Failure atree.adb:808 |
| Error detected at a-exexda.adb:635:15
This suggests that a recent patch that has also been backported to the 4.6
branch
is the culprit.
