Running some apps leave me sometime having an exception in the debugger, so gdb is called. And many times the function that appears when gdb is called is nanosleep(). Should I consider this as a libc issue ?
not at all. gdb is launched because of an exception inside the debugger to ensure that gdb is started, winedbg waits, in the fault handler for some time, to let gdb attach to the winedbg process that's why you see the nanosleep at the top of backtrace the interesting part is to know where the debugger crashed (ie the PC, and the function from the exception frame at the bottom of the backtrace)
A+
