Pulling in misd/phone-number-bundle with composer is causing memory limit to be exhausted

[crmpicco]

I have narrowed down a memory issue in my application to the inclusion of the misd/phone-number-bundle dependency.

I am running a Symfony 3.4 application and when I try and pull in this dependency now I get the following error:

composer require misd/phone-number-bundle
Using version ^1.3 for misd/phone-number-bundle                
./composer.json has been updated
Loading composer repositories with package information

PHP Fatal error:  Allowed memory size of 1610612736 bytes exhausted (tried to allocate 4096 bytes) in phar:///usr/local/Cellar/composer/1.7.2/bin/composer/src/Composer/DependencyResolver/Solver.php on line 220

Check https://getcomposer.org/doc/articles/troubleshooting.md#memory-limit-errors for more info on how to handle out of memory errors.

I can, of course, run composer with no memory limit - but I never used to have to do that until today.

cat /usr/local/etc/php/7.2/php.ini | grep -i memory_limit
memory_limit = 400M

composer --version
Composer version 1.7.3 2018-11-01 10:05:06

My full composer.json looks like this:

If I remove the phone-number-bundle there is no memory limit error and composer completes as expected.

Has there been a recent change to this bundle that could cause a memory issue?
