Are there bug reports?

@ibuclaw I suppose you refer to the ICE.

Here's what I get when trying to compile dub (using a manual command because of -Werror causing the build to fail sooner):

% gdc @build-files.txt -o bin/dub -fversion=DubUseCurl -fversion=DubApplication -I source  -fpreview=in  -freport-bug
/usr/lib/gcc/x86_64-pc-linux-gnu/14/include/d/std/math/exponential.d:587:30: internal compiler error: in layout_aggregate_type, at d/types.cc:562

Looking at https://gcc.gnu.org/bugzilla I found https://gcc.gnu.org/bugzilla/show_bug.cgi?id=112285 and https://gcc.gnu.org/bugzilla/show_bug.cgi?id=112290 which both have small reproducers and have a similar setup to the dub build failure, -fpreview=in causing an ICE.

I don't know how to minimize such an error, nor do I have the time right now to do it, so all I did was remove the flag and add a comment saying why it was removed. I though that it was better to have those 2 bugs solved and see if the error persists in dub rather then opening a new issue that just said "dub fails to build with -fpreview=in".

I'm pretty new to this so, if you think my reasoning wasn't right, I will accept it and try not to do it in the future :)

It's probably PR11285 then.
