a list of stack traces from spinning gdb, plus a bit of the eclipse gdb log
I wrote up a question here which basically states the problem, and somebody
suggested posting to the mailing list, but I didn't see how, so I thought I'd
open a bug.
http://stackoverflow.com/questions/43743703/anybody-have-a-workaround-for-gdb-hanging-while-rendering-pretty-print-in-eclips
I've updated to eclipse neon, I svn updated to the latest
svn://gcc.gnu.org/svn/gcc/trunk/libstdc++-v3/python, and I've just built gdb
7.12.1, all the latest stuff, doesn't help.
I have the pretty printing all working, but every once in a while, trying to
update the variables view, gdb will hang. Actually it spins the cpu. I've
attached gdb to gdb (because I find the idea amusing) and have gotten a number
of stack traces and they're all implying some failure to find a printer and
retrying over and over. Anybody ever see this or have a workaround? It's not
obvious which printer (if it's a single one) is causing the problem, or I'd
just disable it.
Suggestions on how to even diagnose what printer to disable? I google and
google and nobody complains of this behaviour, but having reinstalled
everything, I don't get why it's not happening to anybody else.
Last time I ran into the problem I got some more stack traces and it eventually
hung in one spot. See the attached text file of stack traces.
