Hi,

I am trying to debug a problem that some users have found in the ESEO
decoder in gr-satellites (https://github.com/daniestevez/gr-satellites).

The problem is that after running for a lot of time, the Reed-Solomon
decoder block throws a std::bad_alloc exception, which gets printed out as

thread[thread-per-block[13]: <block decode_rs_general (10)>]: std::bad_alloc

It seems I am able to replicate this on my system.

My question is how to start debugging this. Is there any way in which I
can try to find what in the decode_rs_general block is throwing the
std::bad_alloc exception?

This decode_rs_general block uses Phil Karn's libfec and it doesn't do
any memory allocation, except on initialization, so I find it weird that
it's giving a std::bad_alloc. See the source of the block here:

https://github.com/daniestevez/gr-satellites/blob/master/lib/decode_rs_general_impl.cc

Best regards,

Daniel.
