After somme minor midficiations, I make a try on the winbuilder site.
I was able to build the archive with the static library
but I get again a Bad address error. You can have a look to
https://win-builder.r-project.org/bw47qsMX3HTd/00install.out
I think that Win-Builder is running out of memory. It took some
experimenting, but I was able to reproduce something like this using
the following:
1. Set the swap file in the Windows settings to minimal recommended
size and disable its automatic growth
2. Write and run a program that does malloc(LARGE_NUMBER); getchar();
so that almost all physical memory is allocated
3. Run gcc -DFOO=`/path/to/Rscript -e 'some script'` & many times
I got a lot of interesting errors, including the "Bad address":
Warnings:
1: .getGeneric(f, , package) : internal error -4 in R_decompress1
2: package "methods" in options("defaultPackages") was not found
0 [main] bash (2892) child_copy: cygheap read copy failed,
0x0..0x800025420, done 0, windows pid 2892, Win32 error 299
0 [main] bash (3256) C:\rtools43\usr\bin\bash.exe: *** fatal error in
forked process - MEM_COMMIT failed, Win32 error 1455
-bash: fork: retry: Resource temporarily unavailable
-bash: R-devel/bin/Rscript.exe: Bad address
The above indeed happens if not sufficient memory would be available.
Important to know: This includes unused but committed memory which may
be a lot.
But I doubt it is the case on winbuilder as the machines has 256GB or
more (depending in the machine) and additionally 500GB swap space on SSD.
Best,

Your package is written in C++, but that by itself shouldn't disqualify
it. On my Linux computer, /usr/bin/time R -e
'install.packages("MixAll")' says that the installation takes slightly
less than a gigabyte of memory ("912516maxresident k"), which is par
the course for such packages. (My small Rcpp-using package takes
approximately half a gigabyte by the same metric.)
I'm still not 100% sure (if Win-Builder is running out of memory, why
are you seeing "Bad address" only and not the rest of the carnage?),
but I'm not seeing a problem with your package, either. If EFAULT is
Cygwin's way of saying "I caught a bad pointer in your system call"
(which, I must stress, is happening inside /bin/sh, not your package
or even R at all), it's not impossible that Win-Builder is having
hardware problems. Unfortunately, they take a lot of effort and
downtime to diagnose and could be hiding anywhere from RAM to the power
supply.
