I've tried rebuilding jemalloc and then telegram-desktop again, but to no avail. telegram-desktop dumps core: Process 2936641 (telegram-deskto) of user 1000 dumped core.

The symptom looks very similar to that of https://bugs.gentoo.org/802435. I suspect this is due to dev-libs/jemalloc being merged with USE=lazy-lock (or possibly xmalloc).

That's it! Removing USE=lazy-lock and rebuilding jemalloc does the trick and telegram-desktop starts again. Thanks.
I have no idea what lazy-lock does, but the jemalloc reports sure keep on coming. Is this something that can be solved from telegram-desktop's side at all? Or is this a bug with jemalloc itself? I'd prefer not restricting the use of certain USE flags from *DEPEND... This is practically the only jemalloc-related code that tdesktop has: https://github.com/telegramdesktop/tdesktop/blob/3e8912a53f9a9d4313577a4bccdfbf77ff5c5d59/Telegram/SourceFiles/platform/linux/specific_linux.cpp#L643
I've looked a bit more into this. Apparently lazy-lock attempts to override/intercept pthread_create, by using libdl to grab the "next" pthread_create symbol, storing it in pthread_create_fptr, and calling that from its overridden pthread_create. It does this to find out when the program is multithreading (hence lazily enabling mutex locking mechanisms). Why dlsym() fails, and abort() is called as a consequence, I'm not sure, however. I doubt it's related to LTO, but that, and using mallctl to set the "lazy_lock" option to false from telegram-desktop (it has a fallback in that event), should both be attempted before it's written off as unsolveable.
Maybe related bug: https://bugs.gentoo.org/806292
