A number of crashes are reported in strsclnt in tinderbox subsequent to some of my checkins for bugs 399304, 403957, 353577 .
Here is one of the logs with the crashes :

This is not happening on all platforms. I am trying to reproduce the issue on the same platform so I can get a stack dump.

I reproduced the problem on NSS_3_11_BRANCH and Solaris sparc 64 bit.
The crashes are in the stan code and don't make much sense. The problem seems to be due to the checkin for bug 353577, as it went away when I backed out the patch. I haven't found what's wrong with it yet. My guess is that it has something to do with the NSS_3_4_CODE changes. I'm still investigating.

This is one of the crash stacks . They are all identical.
The problem is always that o2 is NULL .

Comment 3

Removing the PURE_STAN_BUILD macro had zero risk because it is
easy to verify that the PURE_STAN_BUILD macro wasn't defined.

The NSS_3_4_CODE macro is a different story.  In one or two
directories, it was defined in a makefile, which was good.
But in other directories (e.g., lib/pk11wrap), it was manually
defined in the .c files, before including the Stan headers.
So it is difficult to verify that we defined NSS_3_4_CODE
in all the necessary places.  It was possible that in a .c
file we didn't define NSS_3_4_CODE before including the Stan
headers, so that removing the #ifdef NSS_3_4_CODE did not
result in the same code.  I tried to look for such problems
but gave up because it was too tedious.

Julien, fix all the warnings:
warning: implicit function declaration xxx

Comment 5

On the NSS_3_11_BRANCH you missed two files:
$ find . -name "*.h" -print | xargs grep NSS_3_4_CODE

$ find . -name "*.c" -print | xargs grep NSS_3_4_CODE
./lib/pki/tdcache.c:#ifdef NSS_3_4_CODE
./lib/pki/tdcache.c:#ifdef NSS_3_4_CODE
./lib/pki/tdcache.c:#ifdef NSS_3_4_CODE
./lib/pki/tdcache.c:#ifdef NSS_3_4_CODE
./lib/pki/trustdomain.c:#ifdef NSS_3_4_CODE
./lib/pki/trustdomain.c:#ifdef NSS_3_4_CODE

Created attachment 289629 [details] [diff] [review]
Proposed patch

The changes to tdcache.c and trustdomain.c are required.

The other changes are just formatting changes.

We did have the problem I mentioned in comment 3 (we didn't
define NSS_3_4_CODE in crl.c and nssinit.c before including
devt.h), but there was no harm.

Comment on attachment 289629 [details] [diff] [review]
Proposed patch

I've checked in this patch on the NSS_3_11_BRANCH because this
patch is just a missing piece of the patch that Nelson and I

In the CVS commit comment I noted "tbr=julien.pierre", which
means "to be reviewed by Julien Pierre".

Comment 8

Yes, I noticed the problem in nssinit.c and crl.c yesterday (I changed the header files to have #else #error NSS_3_4_CODE not defined) but indeed there was no harm.
Thanks for noticing the problem and checking in the fix.

Comment 9

Yes, that's also how I found out about nssinit.c and crl.c :-)
I then made the NSSSlotStr and NSSTokenStr structures opaque
in devt.h and verified that I could still compile nssinit.c and
crl.c successfully and without compiler warnings.
