https://issues.dlang.org/show_bug.cgi?id=19660 Issue ID: 19660 Summary: 'export' keyword on OSX dynlib globals causing segfaults Product: D Version: D2 Hardware: x86_64 OS: Mac OS X Status: NEW Severity: normal Priority: P1 Component: dmd Assignee: nobody puremagic.com Reporter: redapple82570 gmail.com Created attachment 1732 --> https://issues.dlang.org/attachment.cgi?id=1732&action=edit minimal example (Mac/Windows) [DMD 2.084.0 on macOS 10.12] The presence of 'export' on a global dynlib/DLL variable: eg. "extern (C) export extern __gshared int someValue;" ... is causing inconsistent behavior between Mac/PC: keyword is required for linking against DLL on Windows, but causes runtime segfaults* on Mac. Removing 'export' solves Mac crashes but then Windows linking fails. * initially this issue was discovered due to the globals having incorrect values. But the attached example is segfaulting. LDC2 (1.14.0-beta1) does NOT exhibit the same issue. --
