Hi Andrew,
I get the same error message when a raw disk image cannot be accessed:
$ ./i386-softmmu/qemu -snapshot -m 256 /dev/hda
Could not configure '/dev/rtc' to have a 1024 Hz timer. This is not a fatal
error, but for better emulation accuracy either use a 2.6 host Linux
kernel or
type 'echo 1024 > /proc/sys/dev/rtc/max-user-freq' as root.
*** glibc detected *** double free or corruption (fasttop): 0x09b29120 ***
Abgebrochen
With read access to /dev/hda, everything works fine.
My libc is Debian libc6-2.3.6-15, and the abort message is correct:
QEMU CVS head frees the same memory (bs->opaque in bdrv_close) 2 times.
Older versions of QEMU did not have this bug:
$ qemu -snapshot -m 256 /dev/hda
qemu: could not open hard disk image '/dev/hda'
Regards
Stefan
