Apologies in advance for this being a very vague bug report, but I don't
know how to properly debug this kind of issue (pointers appreciated!)
I find that, using the latest version of gccemacs (commit
#801e19d0ba8e048...) and typescript.el (commit #0fc729787007b5111f...)
Emacs will lock up with 100% cpu usage whenever a TypeScript file is
opened. Interrupting Emacs using SIGUSR2 produces the following backtrace:
Debugger entered--entering a function:
* #<subr F616e6f6e796d6f75732d6c616d626461_anonymous_lambda_10>()
typescript--ensure-cache(515)
typescript--class-decl-matcher(515)
font-lock-fontify-keywords-region(1 515 nil)
font-lock-default-fontify-region(1 501 nil)
font-lock-fontify-region(1 501)
#f(compiled-function (fun) #<bytecode
0x58bf2cebcbf23b5>)(font-lock-fontify-region)
jit-lock--run-functions(1 501)
jit-lock-fontify-now(1 501)
jit-lock-function(1)
redisplay_internal\ \(C\ function\)()
I didn't spot any literal lambda within typescript--ensure-cache so I
assume it's being generated by some macro? Adding the melpa package
repository to the gccemacs docker image, installing typescript-mode and
opening a .ts file also causes the Docker version to lock up with 100%
CPU usage so I assume this is not caused by my config (trying to send
SIGUSR2 to emacs terminated the entire container).
If there's anything I can try out to debug this issue, I'll gladly do so.
Thanks for your amazing work on gccemacs!

The following is extracted from the template produced by
report-emacs-bug, though given that the Docker image locks up too, I
guess most of it isn't of interest anyway:

Well... must say this sounds surprisingly accurate! :/
Closing it :)
