Re: [Openocd-development] SIGSEGV on svn:1198

[Rick Altherr]

I haven't attempted to reproduce but I thought I would mention a few things for those investigating. buf_set_buf() died because the passed in src was bogus. That means the arg was wrong when buf_set_buf() was invoked by jtag_build_buffer() at jtag.c:1228.
