Hi Jon,

A new version of Setup (2.911) has been uploaded to:

  https://cygwin.com/setup-x86_64.exe  (64 bit version)
  https://cygwin.com/setup-x86.exe     (32 bit version)

for me the new setup executables do not work, same for both:

Microsoft Windows [Version 10.0.19044.1415]

D:\System\Software\cygwin-all>setup-x86_64.exe --version

D:\System\Software\cygwin-all>Cygwin setup 2.911

D:\System\Software\cygwin-all>setup-x86_64.exe

D:\System\Software\cygwin-all>Starting cygwin install, version 2.911
User has backup/restore rights
User has symlink creation right

That's disappointing.

Perhaps you can try the following (unfortunately complex) procedure to help me investigate the problem:

1. Using an old setup from https://cygwin.com/setup/, install the gdb and upx packages.

2. Fetch setup 2.911, and the corresponding symbols. Make sure setup is executable.

$ wget https://cygwin.com/setup/setup-2.911.x86_64.exe
$ chmod +x setup-2.911.x86_64.exe
$ wget https://cygwin.com/setup/setup-2.911.x86_64.dbg

3. Decompress the setup executable using 'upx -d'.

$ upx -d setup-2.911.x86_64.exe

4. Run setup under gdb. Avoid elevation so setup stays under the control of gdb. Load the symbol file into gdb.

$ gdb --args ./setup-2.911.x86_64.exe -B
[...]
(gdb) symbol-file setup-2.911.x86_64.dbg
Reading symbols from setup-2.911.x86_64.dbg...
(gdb) r

5. When gdb reports an error, capture a backtrace.

(gdb) bt full
