Hi all!
There's a problem with file-time handling for VVAT.
I found this when expanding HIMEM.SYS from a Windows 98 ISO file.
HIMEM.SYS gets a creation time of "1607-01-19 20:38:32", which is
obviously wrong, but that's not a QEMU problem.
If I put this file to "temp/" and use option "-hdb fat:temp/", QEMU
dumps with 0xc0000005 (access violation) immediately.
I'm not very familiar with GDB, but at least I got this description.
***
Program received signal SIGSEGV, Segmentation fault.
fat_datetime (time=-1, return_time=1) at bswap.h:123
123 CPU_CONVERT(le, 16, uint16_t)
***
This has been tested with QEMU 0.9.1 and trunk.
Johannes?
