Wine-5.18 page fault
by business_kid from LinuxQuestions.org on (#5AB0T)
I'm getting a fairly repeatable crash from wine on the 'back' button of a library program. There was an option to save a backtrace which I did. It's a long harmless enough output after the first bit Code:Unhandled exception: page fault on read access to 0x00010248 in 32-bit code (0x6ccdb84d).

Backtrace:That looks an awful lot like a segfault, which indicates poor software. Last night I had this recurring 100% of the time in one instance, while hardly at all in another. The program itself has been pretty stable for years, and is probably compiles for an i386sx or something very low level like that. Wine is 5.18-staging from Alien Bob. The kernel is 5.4.68-generic.
The only thought that strikes me is that we're 32bit here, in that it thinks it's a '386 and the database is over 4G, even the ext4 disk is 64bit. Does anyone know for sure if that stuff is safely handled?
