--- Comment #9 from Dmitry Timoshkov dmitry@baikal.ru --- (In reply to Anastasius Focht from comment #8)
I consider it fixed (for now) and suggest to drop https://github.com/wine-staging/wine-staging/blob/master/patches/kernel32- PE_Loader_Fixes/0003-kernel32-On-process-entry-store-PEB-address-in-ebx. patch unless there is still a plan to eventually upstream it to mainline.
What do you think Dmitry.
Since this highly depends on compiler behaviour (version, optimizations, register usage) I'd guess that the patch could still be useful for older compilers or not optimal configurations.
