Clang SIGSEGV when compiling BPF target

[epoll-reactor-2]

Minimal code snippet:

#include <linux/bpf.h> // Crashes.
// #include <linux/selinux_netlink.h> // Works like any other header.

int main() {}

Compile command that works correctly:

$ clang-21 -g -I/lib/modules/$(uname -r)/build/include -c c.c -o c.o
OR
$ clang-21 -target bpf -I/lib/modules/$(uname -r)/build/include -c c.c -o c.o

  266 | #include <asm/rwonce.h>
      |          ^~~~~~~~~~~~~~
1 error generated.

Just no header.

Compile command that crashes. Constraints:

1. -g in combination with -target bpf crashes compilation.
2. If program is compiled with only one of the flags: -g or -target bpf, compilation does not crashes.

$ clang-21 -H -g -I/lib/modules/$(uname -r)/build/include -target bpf -c c.c -o c.o

Minimal code snippet:

#include <linux/bpf.h> // Crashes.
// #include <linux/selinux_netlink.h> // Works like any other header.

int main() {}

Compile command that works correctly:

$ clang-21 -g -I/lib/modules/$(uname -r)/build/include -c c.c -o c.o
OR
$ clang-21 -target bpf -I/lib/modules/$(uname -r)/build/include -c c.c -o c.o

1 error generated.

Just no header.

Compile command that crashes. Constraints:

1. -g in combination with -target bpf crashes compilation.
2. If program is compiled with only one of the flags: -g or -target bpf, compilation does not crashes.

Minimal code snippet:

#include <linux/bpf.h> // Crashes.
// #include <linux/selinux_netlink.h> // Works like any other header.

int main() {}

Compile command that works correctly:

$ clang-21 -g -I/lib/modules/$(uname -r)/build/include -c c.c -o c.o
OR
$ clang-21 -target bpf -I/lib/modules/$(uname -r)/build/include -c c.c -o c.o

1 error generated.

Just no header.

Compile command that crashes. Constraints:

1. -g in combination with -target bpf crashes compilation.
2. If program is compiled with only one of the flags: -g or -target bpf, compilation does not crashes.

The command line:
$ clang-21 -H -g -I/lib/modules/$(uname -r)/build/include -target bpf -c c.c -o c.o
is not right.
To compile a bpf program with '-target bpf', you should not include /lib/modules/${uname -r)/build/include since then linux/bpf.h will be the kernel bpf.h and this bpf.h is obviously not the UAPI bpf.h. To compile bpf prog, just do
$clang --target=bpf -g -c c.c
as the your system should already has linux/bpf.h in /usr/include directory.
