The function ves_icall_System_Diagnostics_Process_ExitCode (in
mono/metadata/process.c) calls GetExitCodeProcess (in
mono/io-layer/processes.c), which returns a boolean to indicate success of
failure. Under certain conditions, GetExitCodeProcess may return false without
initializing the exit code pointed to by the *code pointer.
But ves_icall_System_Diagnostics_Process_ExitCode does not check the exit code,
and assumes that GetExitCodeProcess will always initialize the code variable.
This may lead to the exit code remaining uninitialized.
I've observed this happening in my application that repeatedly starts a new
process, waits for it to exit, and queries the exit code. The process always
exits successfully, but sometimes (once in a couple of hunderd times) the
process.ExitCode property will return 10922 (i.e. 0x2AAA, uninitialized value)
instead of 0. When requesting the same exit code again a few lines of code
later, it usually returns 0 again (even if returning 10922 before), so the
issues seems to be timing related.
Reproducible: Sometimes
Steps to Reproduce:
1. Create and start new Process
2. call process.WaitForExit()
3. call process.ExitCode
Actual Results:
process.ExitCode = 10922 (0x2AAA)
Expected Results:
process.ExitCode = 0
