QtConcurrent::run -> crash after a while during read from a HID device - SOLVED
-
Dear all,
I looked on the forum about my issue but I didn't find something similar.
So, I'm developing a small application that works with a USB microcontroller and I'm reading data as HID in order to save actual firmware from the device to PC/MAC.
I launch the reading using QtConcurrent::run method, exactly
@future = QtConcurrent::run (this, &MainWindow::ReadDevice);@On ReadDevice method I call a class comm that perform USB read commands from start_Addr up to end_Addr, 56 bytes at time:
@result = comm->GetData(start_Addr,end_Addr, 56, device->BytesPerAddr, device->pData);@
It works perfectly but after 40 seconds (always @ the same address) the program crash.... and during debug process I receive a message box that tells:
"The inferior stopped because it received a signal from the Operating System"
- Signal name: SIGSEGV
- Signal meaning: Segmentation fault
Anyone could help me to solve this problem?
Thanks in advance,
Placido

Problem found: the fault was generated during write on buffer. Not enough buffer was been allocated.
