[Bug 50108] New: Multiple applications using native API sandboxing / virtualization crash when being relay traced (Adobe Reader 11)
https://bugs.winehq.org/show_bug.cgi?id=50108 Bug ID: 50108 Summary: Multiple applications using native API sandboxing / virtualization crash when being relay traced (Adobe Reader 11) Product: Wine Version: 5.21 Hardware: x86 OS: Linux Status: NEW Severity: normal Priority: P2 Component: tools Assignee: wine-bugs(a)winehq.org Reporter: focht(a)gmx.net Distribution: --- Hello folks, encountered while revisiting some Adobe bugs with native API sandboxing enabled (default). Native API sandboxing works as designed under normal conditions, see my no-relay references later. Relay debugging is a developer / triager use-case.
