I rebuild emacs every day from trunk, but only do a full bootstrap when necessary. I have updated the Mingw compiler this week though, so that could be an issue. I'll try bisecting (and downgrading the compiler) if I see this again. > Also, how was Emacs unresponsive -- did it consume any CPU cycles at > all? Were all the threads locked up, or just some?

Emacs was not consuming any cycles - the system was completely idle. >> Thread 1 (Thread 8744.0xf50): >> #0 0x7c90e514 in ntdll!LdrAccessResource () from C:\WINDOWS\system32\ntdll.dll >> No symbol table info available. >> #1 0x7c90d2aa in ntdll!ZwDuplicateObject () from C:\WINDOWS\system32\ntdll.dll >> No symbol table info available. >> #2 0x7c80df03 in KERNEL32!DuplicateHandle () from >> C:\WINDOWS\system32\kernel32.dll >> No symbol table info available. >> #3 0xffffffff in ??

I'll see if this is reproduceable and try to get more info. AndyM
