Crash in global search

[Andrew Ng]

Hi,

With the latest source, I'm seeing a crash in global when doing a search, e.g.

  global -s -t <sym>

I have traced it down to "uncompress" when "sb_compress" is NULL because "abbrev_open" has not been called.

I've attached a potential fix for this issue which is to explicitly pass a STRBUF to "uncompress" in "output.c".

Cheers,

Andrew
