Description:
------------
We're not able to run all our unit tests on PHP 7.2beta1 because it ends with:

Process finished with exit code -1073741819 (0xC0000005)

I just create a package with a minimum of involved files, so that you have a reproduceable test case.

Just run the test.cmd file: Sometimes the tests run through but sometimes it crashes.

When running this in the whole suite sometimes the tests simply fail (without a crash) but the result is invalid/faulty.

Test script:
---------------
https://customers.setasign.com/php.net/php7.2beta1-bug.zip

Expected result:
----------------
no crash

Actual result:
--------------
crash

Thanks for the report. Somehow I don't reproduce the crash on the latest code base anymore. We've no 7.2 snapshots running yet, but perhaps you could check a latest master one? It's almost same yet.

Thanks.

Anatol, I must admit that I never build PHP from the sources if this is what you mean when you write "check a latest master one"?

I forgot to mention the version I am using (I didn't verified if there are any different behaviours between n/ts and 32/64 yet): http://windows.php.net/downloads/qa/php-7.2.0beta1-nts-Win32-VC15-x64.zip

And again this issue occurs not all the time but e.g. 3 runs work, while the next 3 don't.

Jan,

there is a snapshot service there http://windows.php.net/snapshots/ . You don't have to compile yourself. Locally i tested with the current dev from 7.2 and master, where i didn't repro. With alpha3 the reproducer is reliable.

Thanks.

Ok, I can confirm this: With the current master I cannot reproduce this and all tests went through.

Thanks for checking. Thus looks like it is fixed, next beta should be fine.

Thanks.
