SIGABRT while driving around; related to vehicles?

[Griffinhart]

Version: 0.9-4381-g8c2caf3.

Was driving (southwest) on a Road through some Forest when game abruptly SIGABRT'd. Looks like the crash occurred while processing vehicle movement, or maybe with maps, or maybe because something somewhere wanted to write a string and did some badness regarding string length.

gdb output:

after throwing an instance of 'std::length_error'
    what(): basic_string::_S_create
Program received signal SIGABRT, Aborted.

Thanks for the backtrace, should be helpful tracking down the cause.
From a glance this happened in the mapgen code.
