Re: [Valgrind-users] BerkeleyDB gets bogus errno in Valgrind

[Dima B. <di...@cs...>]

I get the following error with the current CVS sources of valgrind:

==20126== Memcheck, a.k.a. Valgrind, a memory error detector for x86-linux.
==20126== Copyright (C) 2002-2003, and GNU GPL'd, by Julian Seward.
==20126== Using valgrind-cvs-head-2003-07-13, a program supervision framework for x86-linux.
==20126== Copyright (C) 2000-2003, and GNU GPL'd, by Julian Seward.
==20126== Estimated CPU clock rate is 266 MHz
==20126== For more details, rerun with: -v
==20126== 
Root = /root/mcoda/root
mam_journalinit:env_open: Function not implemented
mammoth: mam_journal.c:52: mam_journalenvinit: Assertion `0' failed.
Aborted

This is using Redhat 9, gcc 322, glibc 2.3.2, nptl, and BerkeleyDB 1.4.25.

Thanks
