Some of the new Linux/Android tests were failing in 32-bit code where pointers were being casted via reinterpret_cast<>() to LinuxVMAddress, an unsigned 64-bit type. The behavior of such casts is implementation-defined, and in this case, sign-extension was being used to convert the 32-bit pointers to 64 bits, resulting in very large (unsigned) LinuxVMAddress values that could not possibly refer to proper addresses in a 32-bit process’ address space. The offending reinterpret_cast<>() conversions have been replaced with the new FromPointerCast<>(), which is careful to do sign-extension when converting to a signed type, and zero-extension when converting to an unsigned type like LinuxVMAddress. Bug: crashpad:30 Test: crashpad_util_test FromPointerCast*:MemoryMap.*:ProcessMemory.* Change-Id: I6f1408dc63369a8740ecd6015d657e4407a7c271 Reviewed-on: https://chromium-review.googlesource.com/488264 Reviewed-by: Joshua Peraza <jperaza@chromium.org>
