The stderr was in the previous message. No gripes there either other
than in the startup after the failure.

I did look at the core file and here is what I saw:
#0 0x483cafeb in kill () from /usr/lib/libc.so.12
#1 0x483cd0af in __libc_mutex_catchall_stub (m=1212478892) at /usr/src/lib/libc/thread-stub/thread-stub.c:112
#2 0x4843f0f7 in free (ptr=<incomplete type>) at /usr/src/lib/libc/stdlib/malloc.c:1149
#3 0x081b3efc in AllocSetDelete (context=<error type>) at aset.c:464
#4 0x081b468a in MemoryContextDelete (context=<error type>) at
#mcxt.c:192
In fact it is calling the thread stubs but the applicatino is threaded.
At least, that's what I see from this code in NetBSD.
#define CHECK_NOT_THREADED_ALWAYS() \
do { \ if (__isthreaded) \ DIE(); \
} while (/*CONSTCOND*/0)
#if 1
#define CHECK_NOT_THREADED() CHECK_NOT_THREADED_ALWAYS()
#else
#define CHECK_NOT_THREADED() /* nothing */
#endif
I am going to follow up with the NetBSD team but I pass this on in case
it suggests anything. Note that this still only causes problems on
7.4.6 and not under 7.4.3.
