           Summary: Inline assembler function call
           Product: GDC
           Version: 0.19
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: glue layer
        AssignedTo: braddr@puremagic.com
        ReportedBy: m.faustino@gmail.com


Using inline assembler to make a function call makes the compiler generate a segmentation fault:

//-----------------------------------------------
void main() {
  asm {
    call f;
  }
}

void f() {}
//-----------------------------------------------

With gdc 0.19, dmd 0.162 (gcc version 4.0.3).
