Steam fails to load if compiled with --with-wine64.

Sometimes it'll let you know something has crashed and give you options to
restart various components (including the whole thing) but it makes no
difference.

A. This does not occur if Wine is compiled with --enable-archs=x86_64,i386.
B. It also does not occur using the official Wine binaries (for Ubuntu).

I have tried finding a library and/or kernel issue, but I cannot find it. The
openSUSE logs don't seem to build with --with-wine64. I don't know how those
binaries actually work. Something to do with multiarch setup?

I've tried building with a number of Ubuntu versions, Debian Stable and
Testing, and openSUSE Tumbleweed but the result is always the same.

My build process:

CFLAGS="-g -O0 -pipe"
64 bit: configure --enable-win64 => wine64
32 bit (schroot): configure => wine32
Combine (schroot): configure --with-wine64=wine64 --with-wine-tools=wine32

i386 chroots are need to build 32-bit Wine parts.

$ gcc --version
gcc (Ubuntu 11.3.0-1ubuntu1~22.04.1) 11.3.0
Also tried GCC 12 but no change.

Tried compiling a few older Wines but it made no difference, and eventually hit
other bugs. Doesn't look like a regression.

From what I can see in htop it looks like one of the steamwebhelper processes
is the problem, but I don't know what the problem is exactly.

My guess is there's a problem with the i386 part (or some sort of chroot
madness?). (A) and (B) don't seem to touch 32-bit libraries, at least not in
the same way.

I'm at a loss.

Note: On first run Steam will self-update. This seems to work fine.

No log-in needed to get this far.
