This breaks a lot of PEAR code, btw. Reproduce code: --------------- $x = 'abc'; switch ($x{0}) { default: print "default - works\n"; } switch ($x{0}) { case 'a': print "case 'a' - bus error\n"; } print "done\n"; Expected result: ---------------- default - works case 'a' - bus error done Actual result: -------------- default - works case 'a' - bus error Bus error -------------------- backtrace: (gdb) run bug.php Starting program: /usr/local/book/php/bin/php bug.php [Switching to process 5410 thread 0xb03] Reading symbols for shared libraries . done Reading symbols for shared libraries ............ done default - works case 'a' - bus error Program received signal EXC_BAD_ACCESS, Could not access memory. 0x00229f8c in _zval_dtor (zvalue=0xbb4c10, __zend_filename=0x2c2a24 "/Users/tater/book/php-src/Zend/zend_execute.c", __zend_lineno=203) at /Users/tater/book/php-src/Zend/zend_variables.c:44 44 CHECK_ZVAL_STRING_REL(zvalue); (gdb) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=26281&edit=1
