I'm building a shared library with libpthread and libmudflapth support.
Flags used to compile are: -fstack-protector -fmudflapth
Flags used to link are: -lmudflapth
When trying to dlopen the shared lib at runtime I get:
symbol lookup error: /home/melfar/gcc4/lib/libmudflapth.so.0: undefined symbol:
_start
and the lib fails to open.
Is multithreaded mudflap currently supported for shared libraries?

Hit this same issue. The problem is likely that the -fvisibility=hidden
option is also on the compile line. Removing it makes the problem go
away, at least for single-threaded mudflap.
Produced with gcc 4.2.3, x86_64 under CentOS 4.6.
