>Description:
Today, after I did `make fetchindex' in my /usr/ports, I've tried to do some `make pretty-print-build-depends-list', which resulted in SIGBUS. After some investigation, here's what revealed: simple command
awk -F\| '{print $1}'
dies when processing part of INDEX-6 file, which is attached. I fear that this bug may be triggered in other places of ports/Mk/bsd.port.mk when processing INDEX file (though I didn't get any SIGBUS'es when updating ports today or running pkg_version).
The bug persists on my 3 boxes, all with FreeBSD-6.1-RELEASE, CPUTYPEs pentium3 and pentium4. Turning off both CPUTYPE and -O* optimisations doesn't seem to affect the bug.
>How-To-Repeat:
cd /usr/ports && make fetchindex && cd astro/stellarium && make pretty-print-build-depends-list
>Fix:
None ATM, but here's piece of INDEX-6 file that kills awk and gdb log.
