In `GetGlobalSizeFromDescriptor` we use `dladdr` to get info on the the current address. `dladdr` returns 0 if it failed. During testing on Linux this returned 0 to indicate failure, and populated the `info` structure with a NULL pointer which was dereferenced later. This patch checks for `dladdr` returning 0, and in that case returns 0 from `GetGlobalSizeFromDescriptor` to indicate failure of identifying the address. This occurs when `GetModuleNameAndOffsetForPC` succeeds for some address not in a dynamically loaded library. One example is when the found "module" is '[stack]' having come from parsing /proc/self/maps. Differential Revision: https://reviews.llvm.org/D91344 |
