When I try to build the flutter engine host in release mode on macos, then this fails.
(no issues to build ios release build)

./flutter/tools/gn --runtime-mode=release
ninja -C out/host_release

On a macbook pro 2018 i7 with 16Gb mem, it at one points runs out of memory.
The last few hundred build steps (of 4000+) fail. The build then just freezes
e.g. at
LINK ./shell_benchmarks
or
LINK ./flutter_tester
or
SOLINK libFlutterMacOS.dylib libFlutterMacOS.dylib.TOC
....
It freezes not always on the same step!

I can build the host debug version without any issues
The same build on MacBook Pro i9 with 32Gb mem succeeds.

Are there any minimum memory requirements to build the macos host release?

Will compiling the app against an ios release build and using the host debug build result in the same build as using the host release build?

Next to the issue above with is not based on latest from master, the current master (12th of may) also fails but also creates different compilation errors:

_ld: reference to bitcode symbol '___gxx_personality_v0' which LTO has not compiled in '__gxx_personality_v0' for architecture x86_64

What can i to do resolve these?

Try disabling link-time optimization by passing the --no-lto flag to flutter/tools/gn

This seems to solve both issues
(./flutter/tools/gn --no-lto --runtime-mode=release)

Since this applies to the build tools, could this in any way affect optimisation for the generated flutter app (AOT/release build)?

@jwoelke Yes, it affects optimization. Your builds were working correctly it just takes a LONG time to link with link-time-optimization. Walk away and have a coffee.

Hello! I'm seeing the same issue when building the engine. I'm on MacOS 10.15.7 with Xcode 12.1. I'm trying to build the engine on 1d12d82d9cb54876f58044aa52198d53ec841c3d.

Does the --no-lto affect performance of the generated flutter app or only affects the build time?

I am having the same issue using the master branch and the --no-lto flag
