crash when building thumbs

[steodatus]

Using xnview 1.97.8, libformat 5.76 on windows vista 64, amd phenom II quad.
xnview crashes when building thumbs in folder containing a large number of .jpg files. > 20000.
here's the entry in the event log:
Faulting application xnview.exe, version 1.97.0.0, time stamp 0x4c974973, faulting module xnview.exe, version 1.97.0.0, time stamp 0x4c974973, exception code 0xc0000005, fault offset 0x00001ac4, process id 0x1ce0, application start time 0x01cb7c91c0eeb290.
thumbnail caching enabled with low quality jpeg compression. Also happens with other lossy compression settings.
thumb size is 200x200
crash looks to be happening when windows task manager is reporting a working set (memory) of more than 1975000K for the xnview process.
crash also happening when compression is set to none

reducing the thumb size to 144x144 prevents the crash. however...
- 144x144 is rather small for pictures
- pretty sure that if there are more files in the folder, it will happen again

Exceeding 2GB for a 32bit application will commonly cause a problem. Creating thumbnails is one way of seeing it.
• Memory Limits for Windows Releases

MP will have feature to display thumbnails incrementally, avoiding the need to interrupt process before limit is reached.

hmmm, i can think of a lot of 32 but applications that do not crash when hitting that limit. one example is picasa. photoshop and premiere are also known to be ravenous when it comes to memory. ACD See never had any problems with this particular functionality either.
when can we expect a 64 bit release?
