            Bug ID: 25762
           Summary: LLD [ELF]: linker crashes on -static link.
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: unassignedbugs at nondot.org
          Reporter: grimar at accesssoftek.com
                CC: llvm-bugs at lists.llvm.org
    Classification: Unclassified

Simple program crashes the linker. Looks like eh_frame sections require some
additional handling. 

test.cpp:
#include <stdio.h>
int main() {
   printf("Static boom !\n");
   return 0;
}

~/LLVM/build/bin/clang -static -fuse-ld=lld test.cpp -o test
./test
