I've got one last question too: Win7 x86 or x64?
Please send the sample to me (kay@kay-bruns.de)
[Edit:]
I found the Bug. If a command line plus parameters exceed 4k characters, SuRun crashed.
I kind of fixed it with
SuRun 1.2.1.0rc5 by ignoring command lines >4k length.
This is just a quick and dirty fix.
Almost everything in SuRun relies on that maximum command line length to have a fixed size structure to be transferred between client and service avoiding buffer overflow attacks to the service.
To get real support for large command lines, SuRun almost needs to be recoded.
