LoadLibrary failure: Invalid access to memory location

I am wondering what to do to resolve the following error message:
Error in inDL(x, as.logical(local), as.logical(now), …) :
unable to load shared object ‘C:/Users/VH6B79~1/AppData/Local/Temp/Rtmpui6NFO/file206476487e95.dll’:
LoadLibrary failure: Invalid access to memory location.

This folder location is not actually inaccessible, as R and RStan have no problem writing dozens of other files here in the same session. But it always seems to get hung up on a DLL file at some point. Any ideas for resolving it? It would be much appreciated.

Operating System: Windows 7 Enterprise (64-Bit)
Interface Version: RStan 2.17.3
Output of writeLines(readLines(file.path(Sys.getenv(“HOME”), “.R/Makevars”))):
CXXFLAGS=-O3 -Wno-unused-variable -Wno-unused-function

CXXFLAGS += -flto -Wno-deprecated-declarations

It sounds like some security / permission setting thing or maybe an anti-virus policy that prevents R from dynamically loading the DLL. You shouldn’t have -flto in CXXFLAGS but I doubt that will make any difference.

Actually, for whatever reason, I deleted that flag and now the stan script runs without throwing the error! Thank you!
