Hey DM,

I've noticed pretty much daily core dumps.

Sorry I dont have debugging enabled, and my build is made from a week ago: http://dev.leenooks.net/bbs/sbbs/-/jobs/1267#L1646

using:
make RELEASE=1 USE_DOSEMU=1 NO_X=1 JSINCLUDE=/usr/include/js JSLIB=mozjs185
SBBSDIR=/opt/sbbs install

The backtrace shows:
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/arm-linux-gnueabihf/libthread_db.so.1". btCore was generated by `sbbs -d'.
Program terminated with signal SIGSEGV, Segmentation fault.

#2 0x766d8426 in ?? () from /usr/lib/libmozjs185.so.1.0
Backtrace stopped: previous frame identical to this frame (corrupt stack?)

And the core dumps are quite large 300+MB.

Is this useful at all?

Why don't you update to the latest and build with DEBUG=1 and get a decent
back trace. You can always recompile without afterwards.

What about log file contents?

Slightly. It tells me its crashing in libmozjs. I'd try building with the version of libmozjs included in the Synchronet CVS repository (*not* passing JSINCLUDE and JSLIB on the make commandline). That's the normal/preferred build approach.

Ahh, OK - I was avoiding building libmoz on the Pi as well, it takes soooo long :) I'll add DEBUG=1 to the build as well, incase it continues to happen.

(BTW: Strange, I had a daily core dumps for 3-4 days, and then it went for 4 days happily... But today it core dumped again in the same place.)

BTW: Hope you enjoyed your break, Virgin Islands would be awesome (I've been to Puerto Rico and Haiti in the past)...
