In principle, that can happen.  As I said previously (*1), there are
still some library functions that may call malloc-related functions
internally but their calls are not pretected by BLOCK_INPUT:

    getc, ungetc, fwrite, fclose,
    getaddrinfo, freeaddrinfo

You cannot quit with C-g if inhibit-quit is non-nil (*2).  Can you
check the values of Vinhibit_quit and Qnil if you still have the
debugging session?
