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: unassignedb...@nondot.org
Reporter: gri...@accesssoftek.com
CC: llvm-bugs@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
