Package: libc6-dev
Version: 2.3.6.ds1-13
Severity: normal

A program that is statically linked to NPTL will fail at runtime when
calling raise(3) (and, by extension, abort(3)): 

$ cc -g -Wall -pthread -I/usr/include/nptl -L/usr/lib/nptl -static
test1.c   -o test1 
$ strace ./test1
...
tgkill(0, 0, SIGQUIT)                   = -1 EINVAL (Invalid argument)

This does not occur if the binary is dynamically linked against NPTL,
nor does it occur when linked against LinuxThreads, either statically
or dynamically.

-- Details:

$ cat test.c
#include <signal.h>

int main(int argc, char *argv[]) {
  raise(SIGQUIT);

  return 0;
}
