constant crash on ntdll.dll and qtgui4.dll

hi there,

since installing new qt (build 18.3) on win7 ultimate 64 never been able to make it work properly as it keeps crashing in less than 2 minutes. checked DEP (data execution prevention) but it dind't fix it.

some data : comodo firewall v5, ports open, traffic shaping cfosspeed,

already installed dr ming and here is one crash report about ntdll.dll https://www.dropbox.com/s/kyszoxx8lg4nnpk/slsk1.txt
was not downloading neither uploading

a second crash report a few minutes later while downloading some stuff https://www.dropbox.com/s/f6j1v1cq55ptz0w/slsk2.txt
after this crash the queue evaporated (down and up) and it was working for five minutes. the longest time i saw it working as it keeps crashing

can you help?

This is weird, it crashes in a place where it really shouldn't crash the first time, and somewhere completely random in the second time. I actually suspect something like memory corruption on your machine but I can't say for sure. Another crash report or two should establish whether there's any consistency to these crashes or not, if you're up to it.

Thanks, Nir
