I have found a way to completely crash the Dr. Racket gui in windows 7 64bit just by opening a valid racket file.

Included are files that can reproduce the issue. At least it does 100% reliably on my machine. I spent some time isolating a simple case that still reliably causes the crash.

Unzip the contents.

1. Open DrRacket.

2. Open bug.rkt

3. View -> Show Log

4, Type "debug" into the log messages filter control

5. Run bug.rkt

6. Open "another/repro.rkt"

The crash should occur during the compilation of repro.rkt. On my installation I don't even need to run repro.rkt. It looks like part of the gui that checks syntax or compiles the code is what is bombing.

Thanks,

Curtis

Thank you for your time simplifying the bug.

Do you get an error message with the crash, or does DrRacket just disappear?

There is advice on this page on how to track down such bugs:

When you open DrRacket from the command-line, does it print out an error message then?

I believe the bug is in the runtime's handling of a logging message
when a place is started. I'll push a repair soon.

Curtis: What Racket build are you using? If it's a snapshot, which
snapshot site did you use?

I am using the 6.4 release.

Thanks --- I see that I haven't yet fixed the problem for MinGW-based
builds, like the 6.4 release, so I'll push another repair.
