https://issues.dlang.org/show_bug.cgi?id=24545 Issue ID: 24545 Summary: Problems with m32 mode on Linux Product: D Version: D2 Hardware: x86 OS: Linux Status: NEW Severity: normal Priority: P1 Component: dmd Assignee: nobody@puremagic.com Reporter: erikas.aubade@gmail.com Created attachment 1913 --> https://issues.dlang.org/attachment.cgi?id=1913&action=edit Minimal example to cause a segfault with bindbc. Execute with dub run --single sdlcrash.d --compiler=dmd --arch=x86 There seems to be some sort of weirdness with the output generated by DMD in m32 mode. I initially stumbled on the problem while trying to use bindbc-sdl in dynamic mode--attempting to load the DLL causes a segfault. I've attached a minimal testcase to illustrate this, and can be executed with dub run --single sdlcrash.d --compiler=dmd --arch=x86 This problem doesn't happen in x86_64 mode, or with LDC or GDC in x86 mode. Furthermore, it generates some linker warnings about relocations in read-only sections and creating DT_TEXTREL in a PIE. These warnings seem to be generated with code I feed the compiler, even a trivial hello world--which I'm attaching. The hello world example does not segfault, however. -- |
