Unfortunately your suggestion didn't fix the issue.
Under debugger the problem happen in apr_atomic.c::apr_atomic_dec32()
line:310.
It is inside #if APR_HAS_THREADS.
I tried to set APR_HAS_THREADS to 0 in include/apr.h but got system
lookup
error.
APR_HAS_THREADS ==1 is right and expected, the question is why:
#if (defined(__i386__) || defined(__x86_64__)) && defined(__GNUC__)
&& !defined(USE_GENERAL_ATOMICS)
is not true.
Forget what I was saying about LoggerPtr. Looking at the stack trace
again that isn't the issue. The call to apr_atomic_dec32 that is
crashing isn't in the base class for LoggerPtr, it is in the base
class (ObjectImpl) for some log4cxx object that is defined as a
static. Just not clear which one.
A workaround until we can figure out the issue would be to change
objectimpl.cpp to avoid apr_atomic_inc32 and apr_atomic_dec32:
