drush cex results in Segmentation fault: 11

[powpow12]

Hello,

I have been successfully running drush cex for the past couple weeks until I hit an unclear error today. Here is the error message I received:

/Applications/DevDesktop/drush/drush: line 10: 2122 Segmentation fault: 11 "/Applications/DevDesktop/drush/vendor/drush/drush/drush" "$@"

When I googled this error, it seems to be mostly related to theming and NPM which is not what I am working on. Oddly enough, when I try to do config export through the UI, I get a 500 error so there could be another issue involved.

Any assistance would be appreciated.

Hi. 1. Check the PHP error log 1. Please output the full log with --debug and show the command you are running. Add any site alias info that might be pertinent.

I didn't mention that this was a D8 project and my local environment is via Acquia's Dev Desktop (DD). It turns out, out of the box DD doesn't have php logging set up. I had to do the following:

1. Access my version of php for site, with DD opened cmd + ,
2. go to Config tab
3. in the PHP select, highlight your version and click the Edit link.
4. Search for error_log and remove ';' commented space
5. Set log path error_log = /Applications/DevDesktop/php5_5/dd_php_errors.log and Save
6. reset the server (cmd + 2 and cmd + 1)

Note DD sets log_errors = On and error_reporting = E_ALL in php.ini.

To confirm the config took, I reviewed the php info (on the Config tab click PHP info link)

I again retried the drush command:

this did not add anything to the logs. I went ahead and did a sanity check and in my custom module I wrote to the error log via error_log('this is a test'); and this worked:

Reviewing the logs DD offers, I reviewed the mysql.err and found when I visited the config sync admin page the following errors occurred:
