While attempting to set-up Laravel on an alpine machine i get a general protection error

i used "curl -sS http://getcomposer.org/installer | php" to succesfully install composer.phar for an unprivilegd user ( using alpine-linux very default install ) Required php packages were installed from the alpine epo to have composer install correctly

Code: Select all

apk add php-json php-phar php-ctype php-openssl php-curl

When i run php composer.phar init all works fine until the final stage, then it hits the themattharris/tmhoauth/ requirement and throws a segmentation fault, resulting in the below dmesg output

traps: php[1500] general protection ip:6995a77eed52 sp:78ce42079b28 error:0 in ld-musl-x86_64.so.1[6995a77d2000+86000]

I can repeat this by running

Code: Select all

php composer.phar require

I'd be happy to provide any feedback.
