This is OK, but this is not the call to 'signal' that we are looking
for.  As I said in my instructions:

In the above you have void-variable as error_symbol and the data does
not mention regexp-opt-group.  So you need to type "continue" until
you hit this breakpoint with the correct conditions, and then produce
the backtrace.

Thanks.
