Hey,

binutils 2.36 now defaults to ASLR etc on Windows, so a cygwin compiled linker
will give you:

> peflags -v mydll.dll
mydll.dll: coff(0x2026[+executable_image,+line_nums_stripped,+bigaddr,+dll])
pe(0x0160[+high-entropy-va,+dynamicbase,+nxcompat])

Is this still problematic for cygwin?

The reason I'm asking is because we updated to 2.36 in MSYS2 and are
wondering if
we need to patch this out (or change the defaults) It seems to work as is right
now, but maybe we are just lucky(?).

Some context: https://github.com/msys2/MSYS2-packages/pull/2345

regards
