Glad to announce the second beta for LDC 1.27. Some noteworthy 
changes since beta1:

* Frontend and druntime/Phobos upgraded to yesterday's DMD stable.
* Windows DLL support: some fixes/tweaks and a new -dllimport 
option for greater flexibility.
* Prebuilt Linux and Mac packages can show significant compiler 
performance increases due to newly employing the mimalloc 
allocator.
* Important fixes for -linkonce-templates, DWARF v5 (e.g. with 
linked-in C[++] parts compiled with gcc 11) and bundled dub 
supporting somewhat longer paths on Windows.

Full release log and downloads:

Please help test, and thanks to all contributors & sponsors!

undefined symbol __fieldPostblit and __postblit cause link error 
only with LTO enabled for windows mingw target.

There is more undefined symbols for LDC 1.27 compare to 1.26. My 
code not changed and they used to work with old version ldc.

without LTO all work fine, old LDC link with -flto and -O fix the 
missing symbol,  but 1.26 && 1.27 not work anymore.

Sorry to hear about your LTO troubles; the -O requirement seems 
to be some MSVC specificum of LLD (see 
https://github.com/ldc-developers/ldc/issues/3500), but LTO 
without -O doesn't make a lot of sense anyway. It might have 
gotten worse with more recent LLVM versions if it used to work 
with older LDC versions; I seem to recall that recent LLD got a 
MinGW driver, so you may want to give that one a try via -linker.

For something actionable, please file an issue with according 
reproducible test case. Note that MinGW targets aren't officially 
supported and totally untested, so if it's been working for you, 
that's either sheer luck or insufficient test coverage. ;)

Unfortunately, the CI service we've been using for Linux AArch64 
(Shippable), incl. generating the prebuilt package automatically, 
was shut down. Travis *might* be a successor, but they'd probably 
need to offer better performance or raise the time-out before 
that can happen.

I could set up a cross-compilation build, but I'm reluctant as 
testing would be very limited and regressions quite inevitable in 
the long run. So I'm currently leaning towards waiting for a bit 
and see if another alternative pops up.
