signal 6 in CVS.

signal 6 in CVS.

[Han-Wen Nienhuys]

I regularly get aborts with current CVS. Call trace:

	#0  0xffffe410 in ?? ()

	#16 0x0813deb6 in Source_file::init_port (this=0x85490b8) at source-file.cc:103
	#


the crash always comes from

	  /* Thread has not been suspended, which should never happen.
	   */
	  abort ();

I suspect that make_stringbuf() or one of the related functions in the
call stack forgot to set some sort of mutex lock.

Marius, can you investigate?
