[PATCH] check d_path() error in print-fatal-signals

2007-05-20 Thread Akinobu Mita
d_path() returns -ENAMETOOLONG if buffer length is not enough. But there is no error handling for it in print_vma() which calls d_path() with not enough buffer (We can easily make segfault program which has longer path than 128bytes). This patch allocates enough buffer for d_path() dynamically.
