Short: save_object() on mappings fails
From: Bill Andrulonis
Date: 2002-08-26
Type: Bug
Driver: 3.2.9-dev.450
State: New
See also: b-020916
-- So far unreproducible.
So we've got another problem, this one dealing with mappings being saved
in an object. It has to do with mappings of a certain size, but we're not
quite sure what size bugs them out.
I'm attaching 2 .o files, the before is the .o file after it bugged out,
the after is the restored, correct file (we had to edit it by hand).
I'm not quite sure how reproducible it is yet. We've had it happen a couple
of times. It looks like it has to do with the size, but we're not quite
sure exactly what size it freaks at.
The last version of the driver that this didn't happen would have been 446,
but I'm not exactly sure. I did a mass update to 450.
We're running Redhat 7.3
And Craig Venz noticed it, too:
We've noticed ever since we upgraded to dev450 that using save_object and
restore_object with mappings has become rather flaky - some kind of
strange string limit seems to be imposed on loading mappings, .o files
which used to work just fine now give Illegal Format errors - this would
happen more often than not on mappings of larger size, while smaller ones
have no problem loading. Also, we had an instance of a strange corruption
while saving a large object file containing a mapping - the mapping itself
saved about the first 3 entries, then ended, later on in the text of the
file the rest of the mapping appeared during a string variable.
My guess would be there's some kind of memory overwrite bug in the save
mapping code, but I havent dived into the driver code itself yet to check
it out and see if I could get any more specifics.
If you'd like examples of said corruptions and such give me a yell and
I'll mail appropriate files to you.
Thanks again for the continued work and support.
