Subject: 24.4; gdb stack overflow in regexp matcher
--text follows this line--
Hello,
I am using Emacs GDB Graphical Interface to debug a large C++ project.
When I stop at certain functions, it breaks the GDB interface with the
error message "Stack overflow in regexp matcher".
I did some google search and found that quite a few people also have
this problem. However, it's not clear how to solve the problem. Any
suggestions? Thanks!
Best,
Rhymer
Here are the output from backtrace:

I'm able to reproduce with both 24.5 and 25.0.95. Attaching testcase as
el file to avoid ambiguity. Run as
emacs -Q -l bug-22149-regexp-overflow.el
I'm entirely sure why this regexp triggers an overflow, but one that
doesn't trigger overflow, and I think should match the same is:
"\\([~@&]\\)\\(\"\\(?:\\\\\"\\|[^\"]\\)*\"\\)\n"

[Message part 1 (text/plain, inline)]
This was a while ago, but the effect can still be observed in current master (28.0.50). The exact reproduction no longer works but it's probably just a quantitive change; perhaps the regexp stack has become bigger.
Simplified, and with some character renaming for clarity, the test case is essentially
(string-match (rx "t"
(* (or (not (any "bq"))
(: "b" nonl)))
"q")
(concat "t" (make-string 160000 ?a)))
where the number 160000 can be lowered a bit to avoid the stack overflow.
One way of dodging the error regardless of string size is to swap the two 'or' operands, so that the (: "b" nonl) part, which usually fails, is attempted first. This is because the NFA matcher implements a kind of TCO: no backtrack point on the stack is needed for the last or-clause.
In fact, Noam's proposed workaround, equivalent to
(string-match (rx "t"
(* (or "bq" (not "b")))
"q")
(concat "t" (make-string 160000 ?a)))
works precisely for this reason -- swapping the or-clauses here gives a stack overflow again.
What about this patch for Emacs 27?

It's not urgent, but it is a bug that gdb-mi crashes with a regexp stack overflow for certain strings.
What the patch does is replacing the regexp fragment
(* (or (not (any ?\" ?\\))
(seq ?\\ nonl)))
with
(* (or (seq ?\\ nonl)
(not (any ?\" ?\\))))
Ie, try the least likely branch first (backslash-escaped char) in the inner loop, so that the successful branch is last and won't grow the regexp stack.
The effect is readily seen in an even simpler example:
(string-match "^\\(?:a\\|b\\)*c" (make-string 160000 ?a))
crashes, but
(string-match "^\\(?:b\\|a\\)*c" (make-string 160000 ?a))
works (ie, fails to match).
It was suggested for Emacs 27 since it's a known bug with a simple solution. Then again, it's not a regression from a recent release.

Then again, it's not a regression from a recent release. Let's install this this on master, then. The use cases which trigger the problem are rare enough to not be too urgent to fix. Moreover, we might decide, for different reasons, to bump up the stack size of the Emacs binary, which will indirectly fix this problem by making it less probable. Thanks.

I'm not sure how the C and regexp engine stacks relate to each other in practice -- main() attempts to grow the C stack to accommodate the maximal regexp stack, but SAFE_ALLOCA is set up to use the heap when necessary. Surely we could decouple them more or less entirely, since the extra cost for malloc is bound to be small when a lot of regexp stack is needed.

Surely we could decouple them more or less entirely, since the extra cost for malloc is bound to be small when a lot of regexp stack is needed. I think regex-emacs.c already overrides some of the SAFE_ALLOCA machinery to that effect, does it not?

It uses its own limits, but the mechanism appears to be unchanged. I wonder how important the stack-growing effort in main() really is for regexp performance.
