[racket-dev] Seg fault

Today some conditions met on my machine and DrRacket began to crash almost
immediately after run. So I reproduced it many times.

The results of last several crashes:

*  Seg fault (internal error) at 31a3a4c
   Seg fault (internal error) at 31a3a4c
   Seg fault (internal error) at 31a3a4c

Racket version: (32 bit x86) 6.1.0.2--2014-07-14(c7dd72a/a)
OS: Windows 7 Prof 64 bit

I also decided to try current snapshot 6.1.0.3--2014-07-30(f3a8883/a).
The crashes are repeated:
