Hung setup-x86_64.exe after parsing setup.ini

Mon Aug 12 09:44:00 GMT 2019

After creating a huge custom package, we meet inaccessibility of using setup.exe. It hangs on parsing setup.ini. By doing a little research we've found that this behavior appears when package size is greater than 1GiB (not accurate 1GiB but 1.4GB is enough). We started to investigate setup.exe sources but we stuck in bison sources.

How to reproduce the problem:
1. Make own FTP-repo of Cygwin (I think it could be done without packages at all)
2. Append the addition to setup.ini (from bottom of letter; in my setup.ini it holds from 173244 line)
3. Compress one with setup
4. Start latest (2.897 | 64 bit) setup-x86_64.exe, try to use this repo with default other settings.
5. The freeze happens during parsing setup.xz

"Workaround" is
1. Replace actual size with 1000000000 (at 173260th line of my setup.ini)
2. Recompress one
3. Start same setup utility
4. Parsing setup.xz passed but it breaks by downloading, of course. It's OK.

It's definitely a bug. What's the proper way to fix it?
