I just noticed some more lines in the output of valgrind, that might be
related (or perhaps not,
since it's within some STL code):

Can anyone reproduce this with the latest git?
Yes, I get a SIGSEGV with todays GIT. I attach the last lines output
by valgrind, in case it
can provide some hint on the problem:
