This does not seem to be related to any certain piece of code, becouse I just have to add a dummy declaration like $tmp = ''; and the script runs normally. For example I just wrote code similar to this: <?php trait T1 { public function t1() { return 't1'; } } class Foo { use T1; } $f = new Foo(); $f->t1(); ?> and segfault occurred. But all I have to do is add the dummy declaration within the trait method and the script runs normally: <?php trait T1 { public function t1() { $tmp = ''; return 't1'; } } class Foo { use T1; } $f = new Foo(); $f->t1(); ?> Sometimes the segfault error disappears by just running the script again. All scripts are run from command line, my compile configuration is as follows: './configure' '--with-mysql' '--with-pgsql' '--with-zlib' '--enable-calendar' '--with-curl' '--with-jpeg-dir=/usr' '--with-png-dir=/usr' '--with-gd' '-- enable-bcmath' '--enable-soap' '--enable-fpm' '--with-pdo-mysql' '--with-pdo- pgsql' '--with-pdo-sqlite' '--with-config-file-path=/etc/php54/cli' '--with- config-file-scan-dir=/etc/php54/cli/conf.d' '--prefix=/usr/local/php54' '-- enable-debug' '--with-mysqli' '--enable-mbstring' I've recompile PHP several times. This issue appears to consider all 5.4.* versions. Here's a bugtrace: Program received signal SIGSEGV, Segmentation fault. 0x000000000094dafb in zend_get_function_declaration (fptr=0x1669df0) at /home/maciek/Pobrane/php-5.4.4/Zend/zend_compile.c:3052 3052 memcpy(offset, fptr->common.scope->name, fptr- >common.scope->name_length); (gdb) bt #0 0x000000000094dafb in zend_get_function_declaration (fptr=0x1669df0) at /home/maciek/Pobrane/php-5.4.4/Zend/zend_compile.c:3052 #1 0x000000000094eaf9 in do_inheritance_check_on_method (child=0x16e15d8, parent=0x1680028) at /home/maciek/Pobrane/php-5.4.4/Zend/zend_compile.c:3263 #2 0x000000000094ecaf in do_inherit_method_check (child_function_table=0x16e1118, parent=0x1680028, hash_key=0x7fffffff9db0, child_ce=0x16e10f0) at /home/maciek/Pobrane/php-5.4.4/Zend/zend_compile.c:3288 #3 0x00000000009881ec in zend_hash_replace_checker_wrapper (target=0x16e1118, source_data=0x1680028, p=0x167ff80, pParam=0x16e10f0, merge_checker_func=0x94ec28 <do_inherit_method_check>) at /home/maciek/Pobrane/php-5.4.4/Zend/zend_hash.c:878 #4 0x000000000098826d in zend_hash_merge_ex (target=0x16e1118, source=0x1668390, pCopyConstructor=0x94d531 <do_inherit_method>, size=240, pMergeSource=0x94ec28 <do_inherit_method_check>, pParam=0x16e10f0) at /home/maciek/Pobrane/php-5.4.4/Zend/zend_hash.c:892 #5 0x000000000094ff5d in zend_do_inheritance (ce=0x16e10f0, parent_ce=0x1668368) at /home/maciek/Pobrane/php-5.4.4/Zend/zend_compile.c:3519 #6 0x0000000000953796 in do_bind_inherited_class (op_array=0x16e2270, opline=0x16eacd8, class_table=0x126ce70, parent_ce=0x1668368, compile_time=0 '\000') at /home/maciek/Pobrane/php-5.4.4/Zend/zend_compile.c:4569 #7 0x00000000009b6a49 in ZEND_DECLARE_INHERITED_CLASS_SPEC_HANDLER (execute_data=0x7ffff7f96538) at /home/maciek/Pobrane/php-5.4.4/Zend/zend_vm_execute.h:936 #8 0x00000000009b3741 in execute (op_array=0x16e2270) at /home/maciek/Pobrane/php-5.4.4/Zend/zend_vm_execute.h:410 #9 0x0000000000962f23 in zend_call_function (fci=0x7fffffffa3f0, fci_cache=0x7fffffffa440) at /home/maciek/Pobrane/php-5.4.4/Zend/zend_execute_API.c:958 #10 0x0000000000716989 in zim_reflection_method_invokeArgs (ht=2, return_value=0x16d6960, ---Type <return> to continue, or q <return> to quit--- return_value_ptr=0x0, this_ptr=0x164abb0, return_value_used=1) at /home/maciek/Pobrane/php-5.4.4/ext/reflection/php_reflection.c:2926 #11 0x00000000009b4e57 in zend_do_fcall_common_helper_SPEC (execute_data=0x7ffff7f94a38) at /home/maciek/Pobrane/php-5.4.4/Zend/zend_vm_execute.h:642 #12 0x00000000009b5cfb in ZEND_DO_FCALL_BY_NAME_SPEC_HANDLER (execute_data=0x7ffff7f94a38) at /home/maciek/Pobrane/php-5.4.4/Zend/zend_vm_execute.h:752 #13 0x00000000009b3741 in execute (op_array=0x7ffff0d7e680) at /home/maciek/Pobrane/php-5.4.4/Zend/zend_vm_execute.h:410 #14 0x00000000009762b2 in zend_execute_scripts (type=8, retval=0x0, file_count=3) at /home/maciek/Pobrane/php-5.4.4/Zend/zend.c:1279 #15 0x00000000008e8a1a in php_execute_script (primary_file=0x7fffffffcda0) at /home/maciek/Pobrane/php-5.4.4/main/main.c:2473 #16 0x0000000000abee99 in do_cli (argc=6, argv=0x7fffffffe188) at /home/maciek/Pobrane/php-5.4.4/sapi/cli/php_cli.c:988 #17 0x0000000000abffb9 in main (argc=6, argv=0x7fffffffe188) at /home/maciek/Pobrane/php-5.4.4/sapi/cli/php_cli.c:1361 Expected result: ---------------- Script exited normally, without segfault.
