Bug #81577 [NEW]: Segfault when signal handler raising a fatal error interrupts sleep+negation
From: abecker at mailbox dot org
Operating system: Linux
PHP version: 8.0.12
Package: Reproducible crash
Bug Type: Bug
Bug description:Segfault when signal handler raising a fatal error interrupts sleep+negation
Description:
------------
Run the test script on the command line and press Ctrl+C. The program
will crash.
A crash will occur if sleep is interrupted by the faulty signal handler
and
a negation of any variable with any value follows immediately. Negation
of
a constant will not result in a crash.
Test script:
---------------
pcntl_async_signals(true);
pcntl_signal(SIGINT, function() { 0/0; });
sleep(10);
! $anyVariableWithAnyValue;
