When compiling PHP with --enable-maintainer-zts, setting the "short_open_tag" and "asp_tag" ini settings in php.ini have no effect.
Compiling without --enable-maintainer-zts doesn't this problem.
The values that are used for these ini settings (when compiled with --enable-maintainer-zts) are the default values that are set in zend_set_default_compile_time_values()

I noticed this issue in PHP-5.2.1RC1, but it is also present in current HEAD (and probably also in older PHP versions).

If more information is needed, just ask.

Reproduce code:
<?php echo "long open php tags" . PHP_EOL ?>
<? echo "short open php tags" . PHP_EOL ?>
<% echo "asp open php tag" . PHP_EOL %>

with php.ini containing:

short_open_tag = Off
asp_tags = On

Expected result:
long open php tags
<? echo "short open php tags" . PHP_EOL ?>
asp open php tag

Actual result:
long open php tags
short open php tags
<% echo "asp open php tag" . PHP_EOL %>

While digging a bit deeper I found that zend_post_startup() is only called when ZTS is enabled. This function calls compilers_global_ctor() which in turn calls zend_set_default_compile_time_values(). In that function the values for CG(short_tags) and CG(asp_tags) are reset to the default values, cancelling the effect off setting the ini values.

Removing the call to zend_set_default_compile_time_values() in compilers_global_ctor() seems to solve the problem, but I can not say for sure it won't cause any other problems.

Fixed in CVS HEAD and PHP_5_2.
