Running "test --verbose util/logging/sigsafe_err" gives me an debug-assert in write(STDERR_FILENO,...). Assert that failed is: "(_osfile(h) & FOPEN)"
Here's the call-stack in WinDbg:
MSVCR100D!_write+0x126 test!tor_log_err_sigsafe_write(char * s = 0x00707290 ".====================== ====================================== T=")+0x66 [g:\mingw32\src\inet\tor-project\src\common\log.c @ 463]
test!tor_log_err_sigsafe(char * m = 0x006bae50 "Minimal..")+0xdf [g:\mingw32\src\inet\tor-project\src\common\log.c @ 491]
test!test_sigsafe_err(void * arg = 0x00000000)+0xb0 [g:\mingw32\src\inet\tor-project\src\test\test_logging.c @ 98]
...
It makes sense that "(_osfile(h) & FOPEN)" is FALSE, since in test_logging.c I see:
close(STDERR_FILENO); <<< !!! what good is this? log_err(LD_BUG, "Say, this isn't too cool."); tor_log_err_sigsafe("Minimal.\n", NULL);
If you close stderr, shouldn't handle 2 point to something else? I cannot see it does. All this is on Win-XP SP3, MSVC v16 (debug).
