New Comment:
I finally had time to rectify my ignorance of threads and ran a test.
Threads do share environment variables, so putenv is inherently not
thread-safe. Nevermind.

I've had more time to look into this, and found that the script below
will recreate the crash. Still using http_load -parallel 5, of course.
Oh, and I noticed that I accidentally posted the 4.2.3 bt here. I'll
post the 4.3.1-dev bt tomorrow.
Thanks
<?php
putenv("SOME_VAR=/this/is/some/value/here/dont/you/think");
?>

Bug #21948 is a bit different. The crash we get is always in strlen,
and only occurs under load when we set environment variables in the
script. It sounds like #21948 happens every time, not just under load.
My naive WAG is that the load causes a resource starvation that php
does not catch. Thus a segv. But somehow this is related to environment
variables. Hmm... Perhaps a bug in the section that allocates memory
for env vars?
Thanks

Bug #21948 may be a related issue.

It crashes with other scripts as well. Our developers experienced this
problem, and I found that these two
scripts reliably reproduce it.
We set the Oracle variables in the script because multiple applications
run in one web server instance - they may not use the same version of
Oracle, and they certainly use different sids.
However, when I commented out the putenv/getenv statements, the test
ran cleanly. The "byte count wrong" messages went away too. So we do
have a kludge of a work-around. It would be nice to have this fixed.
I'm not clear why setting environment variables in the php script is a
bad idea. I would expect each thread to have it's own environment...
Thanks,
David

Does the crash happen only with the provided script?
And btw. you should set those envinronment variables
in the system, NOT in the script..
