Detailed Description

Creates a child process for testing. Uses gtest ASSERT_* to indicate failure. The child's output is passed through a pipe and is available via stdout_read_handle(), and the child's input is attached to a second pipe available via stdin_write_handle().

◆ SafeTerminateProcess()

bool crashpad::SafeTerminateProcess (HANDLE process,
UINT exit_code

Calls TerminateProcess().

+

TerminateProcess() has been observed in the wild as being patched badly on 32-bit x86: it’s patched with code adhering to the cdecl (caller clean-up) convention, although it’s supposed to be stdcall (callee clean-up). The mix-up means that neither caller nor callee perform parameter clean-up from the stack, causing the stack pointer to have an unexpected value on return from the patched function. This typically results in a crash shortly thereafter. See Crashpad bug 179.

+

On 32-bit x86, this replacement function calls TerminateProcess() without making any assumptions about the stack pointer on its return. As such, it’s compatible with the badly patched cdecl version as well as the native stdcall version (and other less badly patched versions).

+

Elsewhere, this function calls TerminateProcess() directly without any additional fanfare.

+

Call this function instead of TerminateProcess() anywhere that TerminateProcess() would normally be called.
