http://bugs.winehq.org/show_bug.cgi?id=59963 Bug ID: 59963 Summary: DWARF unwinding crashes on i386 Product: Wine Version: 10.17 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: kernel32 Assignee: wine-bugs@list.winehq.org Reporter: me@purplesyringa.moe Target Milestone: --- Distribution: --- Created attachment 81351 --> http://bugs.winehq.org/attachment.cgi?id=81351 Binary reproducer My exception-heavy code written in Rust using the GNU toolchain has started crashing somewhere between 10.0 packaged by Debian and the current wine-devel packaged by winehq for Debian. The debug logs go through multiple fixmes, eventually reaching "Unhandled page fault on read access", seemingly while parsing DWARF, and then winedbg handles this crash and has an internal crash at the same address. This only reproduces on i386. The binary works fine on Windows. I've attached the binary that reproduces this issue, built by CI (https://github.com/iex-rs/lithium/actions/runs/28744479549/job/85233130634). Alternatively, you can build the binary from source by running `LITHIUM_BACKEND=panic cargo build --tests --target i686-pc-windows-gnu` in the corresponding repo. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
