very strange indeed... i can reproduce it after a variable number of
executions, seemingly between 500-5000 executions. my slightly modified
version:
while true; do
echo '<?php echo "toto tata \n";' | php;
if [ $? -ne 0 ]; then
echo died after ${i:-0};
break;
else
i=$(expr ${i:-0} + 1);
fi;
done
output:
...
toto tata
toto tata
Segmentation fault (core dumped)
died after 4922

the backtrace is equally odd:
#0 0x00007f4f4d05fed0 in ?? ()
#1 0x00007f4f4da25fc7 in start_thread () from /lib/libpthread.so.0
#2 0x00007f4f4e0a55ad in clone () from /lib/libc.so.6
#3 0x0000000000000000 in ?? ()
the fact that restricting it to a single cpu seems to make it go away is
even fishier...
