Sorry for the missing cygcheck.out, the Spamfilter wouldn't let me pass. Ev=
ery package is up to date.
rsync 3.1.2
php 7.0.19
mysql 10.1.19-MariaDB

Hi,

I encountered a rather strange PHP bug I could only reproduce in cygwin=20
(32 Bit and 64 Bit).
If you have a working MySQL-Connection and then run exec('rsync') the=20
next Query produces the Warning:
PHP Warning:  Error while sending QUERY packet. PID=3D15036 in=20
/home/limora/test.php on line 5

See the attached test.php. It should output:
object(PDOStatement)#2 (1) {
   ["queryString"]=3D>
   string(16) "SELECT * FROM db"
}
object(PDOStatement)#2 (1) {
   ["queryString"]=3D>
   string(16) "SELECT * FROM db"
}

but it does output:
object(PDOStatement)#2 (1) {
   ["queryString"]=3D>
   string(16) "SELECT * FROM db"
}
PHP Warning:  Error while sending QUERY packet. PID=3D15036 in=20
/home/limora/test.php on line 5
bool(false)

So far I could reproduce this with the MariaDB from cygwin as well as=20
xampp, so I guess it's not a MySQL problem. I was only able to reproduce=20
this with rsync so far and  no other cli program.

I'm completely stumped as to what could be causing this.

Cheers,
Bj=C3=B6rn=
