} It goes into an infinite loop getting an I/O error on read, according to
} strace.  This is with the standard default dynamic linkage.

This is on linux, redhat 5.2; sorry for not mentioning it sooner.

It's not the zregexparse test, it's the completion test.

With ZTST_verbose=1, I get to:

...
../../zsh-3.1.6/Test/52zregexparse.ztst: all tests successful.
Running test: directories and files

and then it hangs forever.  It appears that the zsh started on the zpty
slave has died, leaving zpty in a read loop getting I/O error.

A statically linked zsh passes all tests successfully.

I noticed that "make clean" doesn't remove the module .so files, so I
explicitly blew them away and rebuilt.  Makes no difference.

Tricking comptest into attaching an strace to the zsh on the pty, I find
this (after reams of output):

I was able to locate the core file, here's a partial stack trace:
