first 1 MB of fft3dn compiling log

Environment: MSYS2/MinGW, package mingw-w64-x86_64-nasm 2.14.01-1 provided by
MSYS2 project

Building LAME MP3 v3.100 using the media-autobuild_suite (a batch set which
automates updating the MSYS2 environment and all sources required to compile a
variety of codecs up to a custom ffmpeg build)

While LAME is built, I noticed in my task manager that nasm was already running
for more than half an hour with the following command line:

E:\MABS\msys64\mingw32\bin\nasm.exe -f win32 -DWIN32 -i
../../../libmp3lame/i386/ ../../../libmp3lame/i386/fft3dn.nas -o fft3dn.o -l

When I interrupted it, the file fft3dn.lo.lst already had a size of more than
40 GiB. I will attach the first MB zipped here.
