Segmentation fault caused by extension=php_curl.dll

[rosasurfer]

When I run the latest Composer (v1.8.4) I get a segmentation fault at the end, no matter which Composer command I execute. The crash doesn't happen if I disable the provided curl extension.
php composer.phar
Any idea?

No crashes for me (XP SP3 x86):
