-    // MinGW libraries currently don't support ASLR

-    // field in its COFF file headers. Since this is what debuginfo
-    // seems to list we parse the symbol table and store addresses as if
-    // the library was loaded at "image base" as well.
-    //
-    // The library may not be loaded at "image base", however.
-    // (presumably something else may be loaded there?) This is where
-    // the `bias` field comes into play, and we need to figure out the
-    // value of `bias` here. Unfortunately though it's not clear how to
-    // acquire this from a loaded module. What we do have, however, is
-    // the actual load address (`modBaseAddr`).
-    //
-    // As a bit of a cop-out for now we mmap the file, read the file
-    // header information, then drop the mmap. This is wasteful because
-    // we'll probably reopen the mmap later, but this should work well
-    // enough for now.
-    //
-    // Once we have the `image_base` (desired load location) and the
-    // `base_addr` (actual load location) we can fill in the `bias`
-    // (difference between the actual and desired) and then the stated
-    // address of each segment is the `image_base` since that's what the
-    // file says.
-    //
-    // For now it appears that unlike ELF/MachO we can make do with one
-    // segment per library, using `modBaseSize` as the whole size.
