[jira] Created: (STDCXX-808) [Sun C++ -m64] SIGBUS in

[Sun C++ -m64] SIGBUS in strstreambuf::seekoff() on empty stream
----------------------------------------------------------------
Key: STDCXX-808
URL: https://issues.apache.org/jira/browse/STDCXX-808
Project: C++ Standard Library
Issue Type: Bug
Components: 27. Input/Output
Affects Versions: 4.2.0
Reporter: Martin Sebor
Assignee: Eric Lemings
Fix For: 4.3
When compiled with Sun C++ in wide mode (with the [-m64|http://docs.sun.com/app/docs/doc/819-5267/gewhd?a=view] option) the following program (taken from the Rogue Wave regression test test_bug11205.cpp) abends with SIGBUS. This happens in both 4.2.0 and on the head of trunk. Suspect a compiler bug.

Martin Sebor commented on STDCXX-808:
-------------------------------------
It happens reliably with 4.2.0. Somehow it got fixed, but I can't find how. The only recent change I can find in this general area is [r418410|http://svn.apache.org/viewvc?view=rev&revision=418410] but it doesn't look like it has anything to do with this.

-------------------------------------
I just tested this on a Solaris 10 machine with a 15D build using Sun C++ 5.9 on the 4.2.x branch and it works fine.
