Description Dmitry V. Levin 2007-01-23 02:18:42 MSK 
current expect no longer works in current build env for binutils testsuite:
$ hsh --mount=/dev/pts binutils-2.17.50.0.3-alt1.src.rpm
hangs in expect:
# strace -p `pidof expect`
Process 12345 attached - interrupt to quit
--- SIGSTOP (Stopped (signal)) @ 0 (0) ---
--- SIGSTOP (Stopped (signal)) @ 0 (0) ---
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
rt_sigreturn(0x6026b0)                  = 0
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
rt_sigreturn(0x6026b0)                  = 0
...
Same happens with testcase from binutils-2.17.50.0.6-alt1.src.rpm

Regression is due to glibc update:
In glibc-2.3.6-alt7 based environment (e.g. Sisyphus/2006/10/02) expect works,
in glibc-2.5 based environment (e.g. Sisyphus/2006/10/03) expect hangs.

пересборка binutils-2.17.50.0.6-alt1 c использованием expect-5.43-alt2
вполне себе удалась (не hasher, i586). На каком именно тесте оно hangs ?
