I'm debugging a slowdown in my data generator for the adapters for
   semibalanced trees stuff.
   I have a lightweight c++ iterator to loop through repository references
   and to find which branch a random commit came from.
   The hang is happening inside the function that uses this iterator.
   I have a breakpoint set when a match is found. It extracts the name of
   the branch and stores it in a static thread local variable, a quick way
   to reuse heap allocation for dynamic strings.
   gdb is presently looping on this breakpoint, despite it being followed
   by a return statement.
