[Unison-hackers] MacOSX Unison still crashing

[Othmar Wigger]

Dear Unison-Hackers

Despite the recent bug fix of May 25th, the MacOS X version of Unison 
still crashes.

We can reliably reproduce this crash:

1. on a remote host, create a rather large file (1 GB)
   dd if=/dev/zero of=bigfile bs=1000000 count=1000

2. sync this with Unison 2.20.2 (SVN version compiled with ocaml 3.0.9.2)
   to a 300 MHz G3 Mac, running OS X 10.4.6, connected with fast ethernet

3. almost every time, Unison crashes after transferring about 500 MB

In Library/Logs/CrashReporter, we find a crash report containing:

Version: 2.20.2 (2.20.2)
Thread: 0
Exception:  EXC_BAD_ACCESS (0x0001)
Codes:      KERN_PROTECTION_FAILURE (0x0002) at 0x00000403

Thread 0 Crashed:

(UnisonToolbar.m:198)

...

The full crash report is at 
http://www.geo.unizh.ch/~pmarchi/crash/Unison.crash.log

Are we right to believe that there is one more bug? Maybe more 
duplicated code?


Cheers,
Othmar
