I am not sure what to do next. I tried this:
You need to display the value of regexp in Lisp syntax. That is done
with the pr command.
The problem is that I saw
(gdb) pr
17213013
which did not seem as useful. That is why I showed the results of
(gdb) pp regexp=137779403
and
(gdb) p *$
For a person as ignorant as I, `emacs/etc/DEBUG' does not go far
enough in telling me what to do in this case. The file helps in other
cases. But in this case, I am trying to try to find out why an older
instance of Emacs runs the command `rmail-summary-delete-forward' more
slowly than newer instance of the same version.
It is likely that you understand what is to be done and consider it
obvious; unfortunately, I do not.
Please, tell me what you would like me to do, understanding that I
know nothing. I will undertake the actions you suggest and try to
write a appropriate section for `emacs/etc/DEBUG' for people like me.
Thank you.
Meanwhile, in another instance of Emacs, but from the same binary and
also taking a long time to run the command
`rmail-summary-delete-forward', I set the breakpoint as before at
regex.c:4168 .
Then:
(gdb) c
Continuing.
Program received signal SIGTSTP, Stopped (user).
re_match_2_internal (bufp=0x8329d8c,
string1=0x40af4785 ....
(gdb) p string1=0x40af4785
$1 = (
const unsigned char *) 0x40af4785 "Date: Tue, 22 Mar 2005 15:36:30 +0300

Mail Returned to Sender\nTo: [EMAIL PROTECTED] is a MIME-encapsulated
message."...
This gave a different result for pr:
(gdb) pr
(88425796 .
Program received signal SIGSEGV, Segmentation fault.

...
The warning in `emacs/etc/DEBUG' mentions a stack overflow,
however, the backtrace did not show any
(gdb) bt

So I tried:
