--- Comment #6 from R Copley <rcopley at gmail dot com> --- > Yes, I'll try and bisect. Just to check, I rebuilt GCC 9.1 using the version of the MSYS2 package-build from before the update to 9.2, and the binaries have ASLR enabled and do show failures with using PCH. Looks like it's something else in the MSYS2 environment that has changed, not GCC. I've brought it up with MSYS2[1]. [1] https://github.com/msys2/MINGW-packages/issues/5719
