Description:
------------
related to: http://bugs.php.net/bug.php?id=39418

i had the same problem and submitted a bug report with gcc.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30819

i used the suggested compile flags and no segmentation fault anymore, which shows it's a php bug - probably since i get following during make install:

/usr/local/src/apache_etc/php-5.2.1_error/sapi/cli/php -n -dshort_open_tag=0 -dsafe_mode=0 -dopen_basedir= -derror_reporting=E_ALL -dmemory_limit=-1 -ddetect_unicode=0 pear/install-pear-nozlib.phar -d "/usr/local/lib/php" -b "/usr/local/bin"

please add "-fno-strict-aliasing and/or -fwrapv" to the c-flags for solaris 2.9 64bit

however: how to fix the Phar archive problem?

It doesn't sound too convincing.
And the fact that the problem is reproducible ONLY on Sparc and ONLY using GCC 4.x makes me wonder what made you think so.

I would prefer to find the roots of the problem instead of applying some magical workaround.

>however: how to fix the Phar archive problem?
Let me see if I can reproduce it with working GCC.

well the gcc people told me so - sorry.

-fno-strict-aliasing seems to be enough to not segfault.

this workaround id not magical. please read the gcc bug report above.

i tried the ltrim patch. it's the same with or without.

thanks for trying to reproduce it.

Hello,

exact same problem (errors), unable to unpack.

OS: Solaris 10
Platform: Sparc
Compiler: Sun Studio 11
C[XX]FLAGS: -xO5 -xarch=v9 -KPIC
(so compiling 64 bits)

I needed the -KPIC since I was compiling a httpd module..
it does not happens on a Solaris x86 compiled 32bits

-ls

I can reproduce this bug on Solaris 10 x86 Update 2 06/06 with
Sun Studio 11 in both 32- and 64- bit.

This really does not seem to be a GCC bug, since this exact same
bug appears with a different compiler:

cc: Sun C 5.8 Patch 121016-05 2007/01/10
iropt: Sun Compiler Common 11 Patch 120759-09 2006/10/24

One of the crashes was caused by GCC bug.
The other one is fixed in PHP sources.
