Could _dl_fatal_printf be considered to change to call raise a signal that dumps the core instead of _exit(127)?

As the code is an assert(), perhaps SIGTRAP or SIGABRT is best?

On my computer any C program compiled with assert(0) dumps a core file, but this glibc issue assert does not dump a core file.

Inconsistency detected by ld.so: ../elf/dl-tls.c: 481: _dl_allocate_tls_init: Assertion `listp->slotinfo[cnt].gen <= GL(dl_tls_generation)' failed!
Command exited with non-zero status 127

This came up while discussing this issue

This is my test program

$ ./a
a: a.c:6: main: Assertion `0' failed.
Aborted (core dumped)


$ cat a.c
// gcc -Wall -o a a.c
#include <assert.h>

int main()
{
    assert(0);
}
