[spam][crazy][log] gdb, thread local, libgit, instruction pointet

[Undiscussed Past Horrific Abuse, One Victim Of Many]

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.
