Unzip onto a computer with Firebird 2.0 RC3 or RC4 installed. Start the Migrate.exe program. Verify the parameters for Firebird and click the "Run" button.

Vlad, I reproduced it in first pass with HEAD.
It crashed in a call to MOVE_FASTER in VIO.

Seems to come from GC.

Thanks, with HEAD i reproduced its too.

Crash is in VIO\delete_record :

if \(prior \!= record\) \{
	MOVE\_FASTER\(prior\-\>rec\_data, record\-\>rec\_data,
				record\-\>rec\_format\-\>fmt\_length\);
\}

prior->rec_len < record->rec_len (1040 < 1176) here

and it seems MOVE_FASTER copied few bytes from not allocated place

Will look at it closer
