Hi Henner,
Thanks for the reply. I am also working on this problem with Des.
The crash occurs on Mac x86_64 and Windows x86 or x86_64. We don't
build on 32 bit mac. Windows compiler is VS2008, MAC is clang. Have
not tested our linux builds.
The crash is in:
const FileDescriptor* DescriptorPool::FindFileByName(const string&
name) const {
MutexLockMaybe lock(mutex_);
...
}
The "this" pointer is NULL. The DescriptorPool singleton methods are
called ( was not created properly?). The
DescriptorPool::generated_pool() is called and appears to be
initialised when stepping through the code. We have triple+ checked we
are linking against the debug libraries and are building debug.
Stack trace below:
