Bug ID: 30198
Summary: Assertion fail when linking elf and coff together
Product: binutils
Version: 2.40
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: medhefgo at web dot de
Target Milestone: ---
I know the following makes no sense to do, but it should error out instead of
crashing.
$ uname -a
Linux debian-amd64 6.1.14-1-lts #1 SMP PREEMPT_DYNAMIC Sat, 25 Feb 2023
11:02:38 +0000 x86_64 GNU/Linux
$ cat test1.c
void a(void) { __builtin_printf("a"); }
$ cat test2.c
void a(void);
int main(int argc, char *argv[]) { a(); }
$ clang -target x86_64-windows-gnu -c test1.c -o test1.o
$ clang -o test test1.o test2.c
/usr/bin/ld: warning: test1.o: missing .note.GNU-stack section implies
executable stack
/usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in a future
version of the linker
