package from source installation fails with cygheap base mismatch error

[drag05]

Updating packages from source suddenly started failing yesterday. Example, updating package 'cli' from source gives the following error:

"C:/rtools40/mingw64/bin/"gcc  -I"C:/R/R-4.1.1/include" -DNDEBUG          -O2 -Wall  -std=gnu99 -mfpmath=sse -msse2 -mstackrealign  -c ansi.c -o ansi.o
      0 [main] make (8644) C:\rtools40\usr\bin\make.exe: *** fatal error - cygheap base mismatch detected - 0xD66408/0xF96408

Following the advice listed under error does not help:

1. Using installr::install.Cygwin(bit=64), I have installed Cygwin64 on my machine for the first time and still does not work.
2. Downloaded the cygwin1.dll (64bit version) and replaced the existing one in C:/cygwin/bin folder as specified and still does not work.

Please advise!

Please make sure the rtools40 usr/bin directory is first on the PATH as explained on the rtools homepage.

@jeroen Thank you for your time! The rtools\...\bin directory was the first on the PATH, I had forgotten to mention this in my post. Also: do I really need to have Cygwin installed? I do not use it at all and installing from source worked before its installation.
Could it be that a sneaky Windows 10 update caused this? Thank you! P.S. Just in case: I have run DISM and sfc utilities and came up with no violations found.

[jeroen]

You should not install cygwin or msys2 separately, everything is included with rtools40.

@jeroen I have uninstalled Cygwin - quite a pain! Returning to the main issue: is there any foreseeable solution to the cygheap base mismatch? Thank you! UPDATE: I have searched for cygwin1.dll on my computer and been unable to find it anywhere. The cygheap error however, mentions it. I wonder why.

[drag05]

@jeroen Solved: switching "Force Randomization of Images (Mandatory ASLR)" to OFF in "Windows10\Security\App&Browser Control\Exploit protection" solved the issue for me. It does not address the root cause though.

[Moodjbow]

@drag05 turning OFF ASLR works also for me but I cannot leave my computer vulnerable this way. This technology is 15 years old now, and still some binaries are not ready for that. @jeroen I have tried both Rtools40 and Rtools42: it starts already with the MSYS2 bash erroring "Could not fork child process [...] DLL rebasing may be required" (and no, rebaseall ends up also with "forked process died unexpectedly" error) Could building rtools with the dynamicbase and high entropy (64-bit ALSR) flags help?

[drag05]

@Moodjbow I am well aware of that! I think I will just ignore or just stop installing from source. I am on ignore mode currently.

Maybe this will help me switch.

The above article states that the ASLR can be turned off program-by-program. I will try for mingw64 only until Rtools becomes ASLR-aware.

@jeroen Turning off ASLR for mingw64 only did not work. The initial error popped up. What other exe(s) in Rtools should I add to turn off ASLR by-program? Please advise, thank you!
