Hi,
I have noticed some problem in the cppdb branch (at least) in combination with
the inband code.
when the usrp instances are destructed, the vector holding the daughterboard
instances is destructed as well, but there seems to be some problem doing the
destruction in the right order. Symptoms are: a) deadlock in the inband
examples, b) gdb stopping in siglongjmp, c) valgrind reporting accesses to
already freed memory.
The attached small patch fixes this problem.
