Thought about how great it would be, if #tuba could group together related notifications. Went to the settings, and there was indeed an option for this. Nice! Such a great app! Thank you, @GeopJr

Ordentlich was los bei der antifaschistischen Demo gegen den Auftritt von Alice Weidel in #hamburg. 😊

How cool is it to be able to just type coredumpctl debug after a program crashed and start poking around in it immediately? While programming, a code generator for my program crashed somewhere in the build process and I was already dreading to cobble together the precise invocation done by the build system to debug it when I remembered coredumpctl exists. Thanks, #systemd ❤️

I now reduced this to a single ~100 lines file that does no dynamic memory allocations. I'm pretty sure I'm not doing something that is undefined behavior. Still getting different results with -O0 / -O2. Even more weirdly, the bug(?) goes away when I remove an assert that only does a simple comparison. Also goes away when I remove certain struct members that are never written or read from.

I'm pretty sure this is indeed a compiler bug 😱

Currently building GCC from source to test against that.

Sooo, if I build a #c program on #gcc once with -O0 and once with -O2, and it outputs something different. And gcc builds it without any warnings, even with -Wall -Werror -Wextra -pedantic. And also UBSan not finding any undefined behaviors.... Assuming all that, have I found a bug in GCC? 😬

(The disassembly gdb spits out for the offending function looks kinda wrong to me, but my ASM skills are a bit rusty...)

[#]Gnome on #Fedora is such a nice, polished desktop experience. Ever since switching to it (maybe about a year ago?), I've been a significantly happier computer user. And the new versions keep on getting better. I don't think I've ever been as happy with my computing situation (maybe with the exception when I got my first computer of my own as a child, but that feeling is hard to beat).
