- Subject: Problem w/ c++,threads,static initializers
i am using cygwin on my Windows2000 and my c++ program segfaults
when using pthread-mutexes. In particular i am using a lot of
mutexes from within constructors of static objects. These constructors
are called at a very early time of execution of the program and do
calls of pthread_mutex_init, pthread_mutex_lock and such. Taken a glance
at the cygwin source i noticed that the static initializers (constructors
of static objects) are run _before_ some user_data->threadinterface is
initialized (look at dll_crt0_1 () in winsup/cygwin/dcrt0.cc). Isnt it
possible to use thread-functions from static initializers?
BTW i am using cygwin snapshot 20030602 compiled with gcc-3.3 since the
out-of-the-box gcc from the cygwin-package is a prerelease and definitely
contains bugs that do not allow it to compile my code.
