Summary: -fmudflapth -lmudflapth problems with -fvisibility=hidden, missing posix_memalign wrapper and pointers in varargs Product: gcc Version: 4.6.0 Status: UNCONFIRMED Severity: enhancement Priority: P3 Component: libmudflap AssignedTo: unassig...@gcc.gnu.org ReportedBy: p...@mandriva.com.br These are just issues I found when attempting to use mudflap: o Mudflap fails to find symbol main in a test application due to propagating -fvisibility=hidden in CFLAGS. o The code also uses posix_memalign to allocate memory on 16 bytes boundaries, what causes a massive amount of violation warnings. o It tells about faults when receiving pointers as arguments to a varargs function. Overall I adapted the code I did want to test, so this is just a suggestion for enhancement. At least adding a posix_memalign wrapper should be trivial, but not sure about the others. Tested on x86_64 gcc version 4.6.0 20110610.
