CVS commit: src/lib/libpthread_dbg

[Nathan J Williams <nathanw%netbsd.org@localhost>]

Module Name:    src
Committed By:   nathanw

Modified Files:
        src/lib/libpthread_dbg: pthread_dbg.c

Log Message:
A couple of READ calls in td_sync_info() were reading into a
pthread_spin_t variable (4 bytes) but telling read that they were
reading sizeof(struct pthread_spinlock_st) (12 bytes). This led to
overwriting other things on the stack, like the return address. Oops.

Fix by changing READ call here (and elsewhere, for future safety) to:
  READ(,, &variable, sizeof(variable))
instead of
  READ(,, &variable, sizeof(type)).

Fixes a crash in gdb when running "thread examine all" reported by
Bill Studenmund.
