[Libreoffice-bugs] [Bug 112536] New: soffice --help displays nothing (Windows command line)

https://bugs.documentfoundation.org/show_bug.cgi?id=112536

Bug ID: 112536
Summary: soffice --help displays nothing (Windows command line)
Product: LibreOffice
Version: 6.0.0.0.alpha0+ Master
Hardware: All
OS: Windows (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: LibreOffice
Assignee: libreoffice-***@lists.freedesktop.org
Reporter: ***@caesar.elte.hu
CC: ***@hotmail.com

I'm uncertain if I tried it after the fix to bug 111908 (possibly not), but now
I get no results when calling "soffice --help" from the command line.
Works from Cygwin shell, but not from Windows command line.

Observed using 6.0 daily build from 2017-09-18.

Mike, are you able to reproduce it?

Cannot reproduce with master from tonight; OS is Windows 10 x64. Aron, could
you please try debugging it? A codepointer is void displayCmdlineHelp(OUString
const & unknown) in desktop/source/app/cmdlinehelp.cxx; supposedly some
function in lcl_Console ctor doesn't return success?

Thanks for the code pointer!
What I see in lcl_Console constructor is that this is false:
if (GetStdHandle(STD_OUTPUT_HANDLE) == nullptr)

If I move into the 'if' in the debugger (set next statement), then it does
display the help.
However, it's not correct, because 'soffice --help' returns immediately, so
it's not holding an active console to print the text to, it just spews the text
out while the user already has the console.

I wonder why the return value is ERROR_ARENA_TRASHED.

It's really hard to find info on this, not sure if any of these forum threads
make sense:

The fix for this caused Bug 121685. When you have have
Settings->Display->Scale=125%, both the UI and content become blurry and hard
to read.
