| Summary | 0001261: segmentation fault in xdebug.so with PHP7.0 version of 'pkgtools' | ||||
| Description | While helping port packages over to PHP7.0 in Ubuntu, I ran across a segmentation fault when running the `pkgtools` command, if the latest version(s) of php-xdebug were installed. xdebug 2.4.0-rc4 & php 7.0.2 The script is bin/pkgtools from http://anonscm.debian.org/cgit/pkg-php/pkg-php-tools.git/log/?h=master-7.0 The core dump occurs regardless of any parameters to pkgtools (i.e., just running `pkgtools` should be sufficient). | ||||
| Steps To Reproduce | I reproduce this by spinning up a VM (technically a chroot, but equivalent for this purpose) with Ubuntu Xenial, and adding a PPA to it (https://launchpad.net/~php-ubuntu/+archive/ubuntu/php7.0). Update and `apt-get install pkg-php-tools php-xdebug` and run `pkgtools`. | ||||
| Additional Information | Derick provided a temporary patch on the ML, but it fails a PHP7 test case. diff --git a/xdebug_stack.c b/xdebug_stack.c index 2df4c99..ce57521 100644 --- a/xdebug_stack.c +++ b/xdebug_stack.c @@ -1147,7 +1147,7 @@ static void xdebug_build_fname(xdebug_func *tmp, zend_execute_data *edata TSRMLS ) { tmp->type = XFUNC_NORMAL; tmp->function = xdstrdup("{internal eval}"); - } else if (edata && edata->prev_execute_data && edata->prev_execute_data->opline && edata->prev_execute_data->opline->opcode == ZEND_INCLUDE_OR_EVAL) { + } else if (edata && edata->prev_execute_data && edata->prev_execute_data->func->type == ZEND_USER_FUNCTION && edata->prev_execute_data->opline && +edata->prev_execute_data->opline->opcode == ZEND_INCLUDE_OR_EVAL) { switch (edata->prev_execute_data->opline->extended_value) { case ZEND_EVAL: tmp->type = XFUNC_EVAL; | ||||
