#38273 [Opn->Fbk]: Incorrect return address after the execution of a signal handler?

ID: 38273 Updated by: tony2001@php.net Reported By: axelluttgens at swing dot be -Status: Open +Status: Feedback Bug Type: PCNTL related Operating System: Mac OSX 10.4.7 PHP Version: 4.4.2 Previous Comments: ------------------------------------------------------------------------ [2007-07-13 07:56:57] axelluttgens at swing dot be Hello Jani, I'll try to test the case with the php5.2-200707130630 snapshot during this week-end. Thanks for the follow-up, Axel ------------------------------------------------------------------------ [2007-07-11 13:05:39] jani@php.net Please try the 5.2 snapshot as requested before. We are going to discontinue support for PHP 4 this year so it is very unlikely that this bug will ever get fixed in PHP 4. But if the bug does not exist in PHP 5.2 it's possible to backport the fix from it to PHP 4. ------------------------------------------------------------------------ [2006-08-02 11:05:58] axelluttgens at swing dot be As a follow-up: a "switch" statement, instead of reproduce code's "if" statement, does not seem to be affected by the problem. So, replacing the while loop in reproduce code with this one: while (!socket_select($r = array($endpoint), $w = NULL, $e = NULL, NULL)) switch ($err = socket_last_error()) { case SOCKET_EINTR: socket_clear_error(); PollSigs(); break; default: echo "socket_select() failed with $err\n"; break 2; } I get the expected behavior back (without having to resort to the "dummy statement" kludge): $ /Volumes/Data/Sources/sigtest.php ^C Warning: socket_select() unable to select [4]: Interrupted system call in /Volumes/Data/Sources/sigtest.php on line 32 Received SIGINT Handling SIGINT ^C Warning: socket_select() unable to select [4]: Interrupted system call in /Volumes/Data/Sources/sigtest.php on line 32 Received SIGINT Handling SIGINT Could this be of some help for narrowing the cause? ------------------------------------------------------------------------ [2006-08-01 11:59:14] axelluttgens at swing dot be Hello Tony, thanks again for your follow up! For various reasons, I am currently really stuck with PHP 4 here. In that sense, PHP 5 isn't an alternative for me yet. But perhaps were you considering a very precise point? Do you want me to try something else?
