Help me to find appropriate worlaround for __builtin_return_address(). For now i'm trying to use ccmalloc (http://fossies.org/linux/misc/ccmalloc-0.4.0.tar.gz/) package to profile memory usage, but i'm stuck with segmentation fault inside there: My backtrace under gdb is: #0 return_address (i=3) at src/callchain.c:1164 #1 0x08050292 in backtrace (skip=3) at src/callchain.c:1294 #2 0x0805548e in _ccmalloc_malloc (number_of_bytes=96) at src/callchain.c:4306 #3 0x08055ad8 in ccmalloc_malloc (number_of_bytes=96) at src/callchain.c:4590 #4 0x080568ed in malloc (n=96) at src/wrapper.c:318 #5 0xb7c8fc7c in ??

It would be nice to have same functionality as gdb has for "where" command -- Kind regards, Sergey Ivanov
