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

and __builtin_return_address(3) returns 0x80568ed
__builtin_return_address(4) returns 0xb7c8fc7c
and __builtin_return_address(5) - segmentation fault.
It would be nice to have same functionality as gdb has for "where" command

Kind regards,
