Dear Maintainer,
Wine cannot execute position-independent (PIE) host executables via
CreateProcess()
The problem arises from the fact that `create_process_impl()` in
`dlls/kernel32/process.c` ultimately calls `MODULE_get_binary_info()`
in `dlls/kernel32/module.c` which detects PIE exectuables as ELF
shared objects and thus sets `info->type = BINARY_UNIX_LIB;` instead of
`info->type = BINARY_UNIX_EXE;`. I do not have enough knowledge about
the precise way that Winelib apps are implemented or supposed to work,
but the fact that PIE executables are in fact ELF shared objects and
not ELF executables according to the ELF header, causes Wine to detect
these as Winelib apps and ultimately invoke the wrong process creation
path.
As Debian 9 Stretch switched to PIE by default, this basically affects
all native executables. Non-PIE executables work fine.
Wine 1.8.7 is also affected, as is the current Wine development branch.
Upstream bug report is at https://bugs.winehq.org/show_bug.cgi?id=43217 .
