GDB Overflows when entering a function

[LoPiTaL]

Hi everybody!
I am having a problem when trying to debug a function: when the debugger stops in a breakpoint inside the function, no local variables information is shown, the debug controls (Step Over, Step Into, and so) don't work and after several seconds a window with the message "The gdb process terminated unexpectedly (code 3)" appears.
If I set the breakpoint in the caller function, then everything works fine, until I step into the called function, when the debugger hangs up once again.

The "Debugger Log" window, shows the following:

@>~"../../../../src/gdb-7.5.1/gdb/utils.c:1081: internal-error: virtual memory exhausted: can't allocate 2147450881 bytes.\nA problem internal to GDB has been detected,\nfurther debugging may prove unreliable.\nQuit this debugging session? "

~"(y or n) [answered Y; input not from terminal]\n"
~"../../../../src/gdb-7.5.1/gdb/utils.c:1081: internal-error: virtual memory exhausted: can't allocate 2147450881 bytes.\nA problem internal to GDB has been detected,\nfurther debugging may prove unreliable.\nCreate a core file of GDB? "
~"(y or n) [answered Y; input not from terminal]\n"@

So, it seems that the GDB debugger somehow overflows.
There is any workaround to prevent this?

I am working under Windows 7, using Qt 5.2.1 (I have downloaded the package "Qt 5.2.1 for Android (Windows 32-bit)"

Thanks in advance,
