It is a bit simple to say it is due to a Gentoo bug. It is not like we add many 
patches on top of PHP anymore. The few patches we have are mainly related to 
patching the build system.

As mentioned, this segfault had nothing to do with PHAR. It is just the only time 
that php itself is being executed. In our case, the bug was compiling PHP with 
gcc 4.7 under certain conditions.

I should have said CFLAGS_CLEAN I think, since that's what cli builds use.

I just ran into this on SPARC Solaris 5.9, php-5.3.x and 5.4.x. I remembered that long ago, way
before phar, I had php coredumping when running tests. According to Andy Poliakov that was the
result of a change in gcc's behavior, esp. when building code that interacts with openssl. Back
then he suggested adding -fno-strict-aliasing to the CFLAGS in the main PHP Makefile.

So I did the same in php-5.4.14, and voila, it gets past the phar stage and runs all tests fine.
It's nothing to do with phar, it's just that 5.2.x and earlier weren't trying to use
the mis-compiled php for anything during make. Anyone with this problem may want to try that.

Apparently this is due to Gentoo bugs or such, please a) try running  ./sapi/cli/php -m
 or such in the working dir after building PHP, maybe under gdb. And then verify the patches ...

php-5.3.20 # make

Generating phar.phar
make: *** [ext/phar/phar.phar] Segmentation fault

Gentoo.
