+Subject: [PATCH 41/N] Cygwin: pty: Fix 'Bad address' error when running
+ 'cmd.exe /c dir'
+
+- If the command executed is 'cmd.exe /c [...]', runpath in spawn.cc
+  will be NULL. In this case, is_console_app(runpath) check causes
+  access violation. This case also the command executed is obviously
+  console app., therefore, treat it as console app to fix this issue.
+
+  Addresses: https://github.com/msys2/msys2-runtime/issues/108
+
+This is a backport of 08281cf4cc (Cygwin: pty: Fix 'Bad address' error
+when running 'cmd.exe /c dir', 2022-10-22).
+
+The original patch that was replaced by this commit had this additional
+information that is now sadly lost in Cygwin's history:
+
+In 2b4f986e49 (Cygwin: pty: Treat *.bat and *.cmd as a non-cygwin
+console app., 2022-07-31), we introduced a bug fix that specifically
+looks for a suffix of the command's file name.
+
+However, that file name might be set to `NULL`, namely when
+`null_app_name == true`, which is the case when we detected a
+command-line `cmd /c [...]`.
+
+But the commit mentioned above did not account for that possibility,
+instead assuming that it always has to check the file name for a `.bat`
+or `.cmd` suffix. As a consequence, `cmd /c [...]` invocations are
+completely broken in v3.3.6, resulting in a `Bad address` error.
+
