Description:
------------
Building PHP 7.1 inside the pkgsrc framework on Solaris 11.2/sparc using GCC 4.8.5, the step "Generating phar.phar" fails with

Generating phar.phar
PEAR package PHP_Archive not installed: generated phar will require PHP's phar extension be enabled.
gmake: *** [ext/phar/phar.phar] Bus Error (core dumped)
*** Error code 2

The failing binary is the php interpreter build in the preceding steps. The stack trace looks like this

The same code compiles without problems on Solaris 11.2/i86 and the same GCC version.

Please try again after doing

  ./config.nice --without-pcre-jit

Also, which PCRE version do you use?

Without PCRE-JIT, the package builds successfully. I use the PCRE that comes bundled with PHP 7.1.0.

pkgsrc currently provides PCRE 8.39 and PCRE2 10.22, in case those are more recent versions than the bundled one.

So this is apparently a PCRE-JIT based issue.

PHP 7 ships PCRE 8.38, because there have been issues with
8.39[1]. PCRE2 is not yet supported.

I have been told elsewhere by someone who knows SLJIT:
"It crashes while emitting, not when running jit code. My bet is that pcre emits a jump to a dead label"

My current workaround consists of:
 $ cd ext/pcre
 $ wget https://netix.dl.sourceforge.net/project/pcre/pcre/8.40/pcre-8.40.tar.gz
 edit upgrade-pcre.php replacing 'tar' command with 'gtar'
 running $ php upgrade-pcre.php

Afterwards building with gmake finishes successfully 

I would also suggest reviewing Makefile after running ./configure script
Since Solaris supports 32/64 bit simultaneously, sometimes you see Paths to 32-bit shared libraries while compiling 64 bit php

Here is my patch Script for compiling on T5 Server (sparcv9):

perl -pi.back -e 's/-[LR]( ){0,1}\/opt\/csw\/lib\/gcc\/sparc-sun-solaris2.10\/4.9.2/-avoid-version -module/g;' Makefile
perl -pi.back -e 's/\/opt\/csw\/lib$/\/opt\/csw\/lib\/64/g;' Makefile
perl -pi.back -e 's/usr\/ucblib/usr\/ucblib\/sparcv9/g;' Makefile

As of PHP 7.3.0, PCRE2 is required.  I'm not sure whether similar
issues exist there regarding Solaris, but this would obviously be
an upstream issue.
