Thank you for your bug report. This issue has already been fixed
in the latest released version of PHP, which you can download at
http://www.php.net/downloads.php
Yes, this was fixed with #71943.

This is very likely a duplicate of #71943 which is fixed in 7.0.6

Well, I wrote too fast, we're still having issues with this, even with the patch :-/

We have the same issue here. The code works perfectly with PHP 5.6 but in PHP 7 it breaks. What do
something like that :
- Create PDO object
- Make a prepared statement (EXEC a Stored Proc with 16 parameters)
- Bind params with ->bindValue
- Execute (returns data correctly)
- Make an other prepared statement (EXEC same Stored Proc, I know I could reuse the same statement,
but I've been able to produce this bug that way)
- Bind params with ->bindValue
- Execute (it crashes, sometimes segfault, sometimes the query gets truncated and fails on SQL
Server)
The provided patch fix this bug

I can confirm that this problem also exists on OSX with FreeTDS 0.95.21 and I can also confirm that
the attached patch solves the crash.
Also, the backtraces in lldb are all over the place depending on how the PHP code looks, but the
crash is always in emalloc().
