Wow Brian, what a rude response. I definitely followed the problem reporting
guide, and didn't realise you'd need information overload that probably doesn't
relate to the case at hand. When reporting bugs I always give as much info as I
believe is needed in helping, there's no need to snap.
I gave lots of information, such as:
- It applies to all bundled versions of PHP from the `setup-x86-64.exe`.
- That I've reproduced it on multiple (two) machines, including one of those
being a machine that has never had (and so a fresh install of) Cygwin with just
PHP added.
- Compiling PHP from source doesn't produce this issue so it's something to
do with the bundled version only
For extra information, both machines tested are:
- Windows 10 64-bit (10.0.18363)
- One machine is 16GB, the other 8GB RAM.
- All PHP versions from the `setup-x86-64.exe` (7.3.4-1 and 7.1.16-1)

Nope, as shown in the output of my example, the memory limit is set to 128MB:
> Output:
> $ php test.php

Here, the message was included in my initial email: > PHP Fatal error: Out of
memory (allocated 4194304) (tried to allocate 2097184 bytes) in
/c/Users/JackBlower/tmp-safe/test.php on line 5

Nope all 64-bit, I would've mentioned if not.

See the output below for some more info, either way this is a pre-packaged
version of PHP with very little changed from default configuration.

Hey Andrey,
I've tried your script and I hit the 128MB limit, as expected. So maybe it's to
do with the `http` wrapper. Could you try my version of the script please and
see how you get on?
I first bumped into this problem when I rolled back from composer 2.X to 1.X
which uses more memory.
I generated an 800MB file using: ` fsutil file createnew 800mega 838860800` and
then ran your script you provided substituting your backup for the 800 MB file
I generated.
The output of the script is below:
```
$ ./test-mailing-list.php
#!/usr/bin/env php
<?= file_get_contents(__FILE__);
phpinfo(1);
echo ini_get('memory_limit'), "\n";
print number_format(strlen(file_get_contents('800mega')));
phpinfo();
phpinfo()

```
Notice how this time it's running out of memory at 128MB and has the "Allowed
memory size" error instead of the "Out of memory" error from before.
Many Thanks,
Jack
