Each time I got St9bad_alloc , I already tried many times with old files, with clear version (without old files).
After error it stop sync.
Each time (after restart) it starts to index/sync from beginning of time Litecoin history.
Didn't find something useful in google, best try was -dbcache=2000 from thread on bitcointalk, but it didn't help.

This happens after row of my mistakes:
1. was not enough space on local drive where was litecoin.
2. after restart it start to sync and I got some error then I without thinking twice reinstall Litecoin Core above.

Now I have enough space and try on ssd and hdd. With old files and on blank space - same result.

Windows 7  Intel Quad Core x86 8Gb, also tried on Windows Vista x86 Core 2 Duo 3Gb.

Currently problem reproduced:
Litecoin Core x86
Litecoin Core x86 (I assume rc1)
Litecoin Core x86

Success on Windows 7 x64 Core 2 Duo 4Gb, Litecoin Core x64 sync successful, It took no more than 3-4 hours.
Success on Windows 7 x86 Quad Core 8Gb, Litecoin Core x86 sync successful, took 7.5 hours.

However, problem persists on Litecoin Core 0.10.x 32bit (x86).

The bad_alloc exception is thrown when a new variable was attempted to be created, but there wasn't enough available storage (in this case its system memory).

Some things you could try are setting your dbcache value higher, increasing your systems page file size, observing the amount of free memory on your system using task manager -> Performance -> Memory to find out what process is consuming it all.

Thanks for answer.

My first assumption was that I install additional memory (4Gb→8Gb) few month ago, but when it fall down on another pc...
I think in Litecoin Core is some kind of bug that must be fixed. Because it didn't happens before.

I sync blockchain on x64 then move it to my x86. Works fine.
