POSTGRESQL BUG REPORT TEMPLATE

Severity : serious

Summary: postmaster/linux kernel unaligned trap errors

System Configuration
--------------------
Operating System : Linux 2.2.10 (Redhat 6.0)

PostgreSQL version : 6.5

Compiler used : egcs-2.91.66

Hardware:
---------
DEC Multia (Alpha 166mhz), 32mb RAM

Versions of other tools:
------------------------
gmake 3.77, flex 2.5.4

--------------------------------------------------------------------------

Problem Description:
--------------------
It looks like whenever something calls the portmaster, it spews out four lines of console/system log messages:

portmaster(6329): unaligned trap at 0000000120144ee0: 000000011fff9781
portmaster(6329): unaligned trap at 0000000120144ee0: 000000011fff9782
portmaster(6329): unaligned trap at 0000000120144ee0: 000000011fff9783
portmaster(6329): unaligned trap at 0000000120144ee0: 000000011fff9785

The database is working fine (running the regression tests as I type this), but this constant messaging into the system log is annoying.

--------------------------------------------------------------------------

Test Case:
----------
Happened with postgres 6.4.2 and 6.5 on the same system and kernel build. I suspect its something in the code that happens on any Alpha box running Linux 2.2.x from a Redhat 6.0 install.
