Hi Jani,
Unfortunately this patch doesn't fix the bug.
I'm not sure if it fixes module dependency issues (let me know how to
check it), but the original bug has the same two problems.
1) Possible infinity recursion in php_log_err()
2) Uninitialized DATEG(tzcache. It's initialized only during RINIT() so
any error messages befor this may crash PHP.
To test it I just inserted a warning message into main.c around line
2130, right before module_initialized assignment.
+ zend_error(E_WARNING, "test");
module_initialized = 1;
Then run something like this
$ sapi/cli/php -n -ddate.timezone= -derror_log=/tmp/php.log -r 'echo
"ok\n";'
/home/dmitry/php/php6/Zend/zend_hash.c(91) : Bailed out without a
bailout address!
It may bailout or crash.
Thanks. Dmitry.

Added files:

Modified files:

Log:
- Fixed bug #48247 (PHP crashes on errors during startup)
#
# This was sum of many little things:
# 1. Wrong assumption made in order_by_dep.awk on the ordering
# (that script was done prior to adding runtime deps..?)
# 2. request shutdown calls weren't done in reverse order like all other
# shutdown funcs are called.
# 3. config0.m4 rename is necessary for keeping things simple.
