    _______________________________________________________

Details:

TLA 'make test' results in a SEGV in 'tla' at the start of 'test-mirror.sh'.

Configure command used:

../src/configure --prefix=/opt/gnu \
    --with-cc=gcc \
    --config-shell /opt/gnu/bin/bash \
    --with-posix-shell /opt/gnu/bin/bash

tla 1.3.5 built on Solaris 8/SPARC with GNU toolchain (gcc 4.1.1), using
'bash' as the config and posix shell (also used: ksh).

"make test" terminates with a SEGV starting 'test-mirror.sh', on line 16:

  setup_with_trivial_archives

Stepping through the test by hand, the point at which the SEGV occurs is in
'test-framework.sh' line 153 (in 'setup_with_trivial_archives'):

  tla import -S -L 'initial import' 1>/dev/null

Redoing the test, running the above command in GDB:

* creating version address@hidden/hello-world--mainline--1.0

Program received signal SIGSEGV, Segmentation fault.
0x000b1dcc in sha1_process_blocks (buffer=0xffbee342, len=320, ctx=0x189378)
    at <SNIP>/tla-1.3.5/src/hackerlab/hash/sha1.c:370
370               x[t] = NOTSWAP (*words);

NOTSWAP is a no-op on SPARC (BIGENDIAN).  Other values:
  words = (const t_uint32 *) 0xffbee342
  *words = 1382381161
  t = 0
  x[t] = 0


Can't see why the reported line would cause a SEGV.  Possibly a buffer
overflow earlier?
