I have some complicated code that is getting an exception deep inside an eval (specifically "Can't use an undefined value as a symbol reference"). This happens about 1 in every 100,000 transactions, from one of several dozen possible code paths. Without a stack trace I'm pretty stuck.
Is there a way to get caller() information through eval, at the eval level? I know (example below) how to print it locally from a method. But if I don't know in advance where the problem will come from, can I get a stack trace later, bubbled up to the eval?
Note that Carp, I think, won't work, since the exception is caused by a perl error, not an explicit die/carp/cluck.
print "Error $@";
#want to print stack trace HERE!
print "This is level2\n";
print "This is level3\n";
$i = 0;
while(($package, $filename, $line, $subroutine)=caller($i++))
print "caller($i)=$package, $filename, $line, $subrout
$zero = 0;
$zero = 100 / $zero;
