Crash happens in dlopen() code when trying to load the library. Crash does not happen when library is
not DTrace instrumented . Additionally, crash does not happen with default Solaris 10 GCC 3.4.3 and
it does not happen if main executable is instrumented.
So , just check for this specific situation (32 bit, GCC3.4.6 , Solaris) and disable Dtrace in shared libraries.
We have only single plugin so far that is instrumented (ha_example)
fix excessive relinking that results from rerunning
dtrace -G second time on the objects that come into
static library.
The reason for relinking is that dtrace -G changes
timestamp for the object file, which in turn results
in re-archiving the mysys on next time make runs,
which causes relinking of the whole mysql, because
everything depends on mysys.
The fix is to copy objects into temp before running
dtrace -G in mysqld pre-build step. This way dtrace
does not affect the object timestamp.
Rerun dtrace -G on all objects that can contan dtrace probes (also objects that are
part of static libs) before linking mysqld to produce dtrace_probes_all.o and link
dtrace_probes_all.o with mysqld
This ugly workaround was inspired by handling dtrace using autotools.
