Source: dmalloc
Version: 5.5.2-2
The test program dmalloc_fc_t that is run after compiling fails badly.
The build continues anyway, but it indicates a problem with the library.
Some excerpts from a gdb session follow..
(gdb) backtrace

turns out ebp is never written...
But.. the return.h file's GET_RET_ADDR uses assembly code that reads it..
I wonder if it might be that -fstack_protector
