Description

TYPO3 V6.2 maybe a bug in compressing the css-files!?

e.g.: A css3 parameter like width: calc(100% + 16px); does not appear in the compressed CSS-file when config.compressCss is set to 1!

Setting the parameter to config.compressCss = 0, the "calc"-item will be there!

I experienced similar behaviour with following difference: the compressor removes the whitespaces, which results in an invalid rule:

width: calc(100% + 16px);

becomes:
width: calc(100%+16px);

But "+" and "-" must be wrapped with whitespaces: http://www.w3.org/TR/2006/WD-css3-values-20060919/#calc

I digged around in the compressor and will push a possible solution

This patch leads to PHP segfaults on PHP versions with older PCRE versions. It will be reverted in #64950 for 6.2 for now, and master will get a PCRE version check in install tool.

Please see the related issue for more details.

This patch could potentially be fixed again in 6.2 if a regex can be found that does not crash php ...
