We don't use IASM implementations. -- Configure issuemail: http://gdcproject.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching all issue changes.

The fibers which are offered by the WinAPI are not a suiteable replacement. -- Configure issuemail: http://gdcproject.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching all issue changes.

GCC doesn't do naked outside of ARM, AVR, MCORE, RX and SPU. http://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html

There are two solutions to this that don't involve using the WinAPI.  The first is rewriting the fiber implementation to not need naked.

Or putting the switchContext function into an external file as done on some systems.

  version( AsmExternal )
    extern (C) void fiber_switchContext( void** oldp, void* newp );

Working fiber code for that function should be in the mingw repo.  It's just disabled as I never got around to externalizing it.  I won't get around to it until I finish getting GDC working with 4.8.0.

Going to update this title to properly reflect what needs to happen.
