GDB Debugging: Application termintes with SIGTRAP

Question

Have been trying to remote debug an application running on my target using GDB. The target is Armv6 based, the OS is linux and the application is a QT based Multithreaded application.

I am able to set the break point. But when the break point is hit, program gets crashed along with SIGTRAP.

Hint: I am able to run another small sample Multithreaded QT-App on the same target.

What could be the problem?

GDB Log as follows

Breakpoint 1 at 0x4ad52c: file <> , <>. (2 locations) (gdb) c Continuing.

Program terminated with signal SIGTRAP, Trace/breakpoint trap. The program no longer exists. (gdb)

You have maybe a solution here:

http://sourceware.org/gdb/wiki/FAQ#GDB_does_not_see_any_threads_besides_the_one_in_which_crash_occurred.3B_or_SIGTRAP_kills_my_program_when_I_set_a_breakpoint.

Hope this help.

Regards.
