Re: [Discuss-gnuradio] gr-howto OOT tutorial crash

[Vipin Sharma]

I can try re-building the OOT module.

I don't think I know how to '....with logging same-same as GR's'. I have two questions:

1) How do I know how GR was built? With logging?

2) Assuming I know the answer to 1) above, where do I change things so that OOT compiles with with same setting for logging?

Maybe you're hitting the logger_ptr bug? See < https://github.com/gnuradio/gnuradio/issues/1383 > for more info. It happens when GR is built with logging enabled but not log4cpp, and then the OOT is built either with logging enable and log4cpp or logging not enabled. The "free" on gr::block ends up corrupting the stack because the logger_ptr is of the wrong size in the OOT block (when compared with that compiled into gnuradio_runtime). Not sure if this is the issue here, but this is happening during gr::flowgraph::clear (which just clears the blocks and then edges), so, maybe? An easy test is to rebuild the OOT with logging same-same as GR's. - MLD
