Reproduce after rm ~/.wine/.update-timestamp On Linux the reported byte position is twice byte 0/11. In addition, when gecko is present, there are 5 occurrences of warn:heap:validate_block_pointer Heap 0x110000: pointer 0x40248080 is not inside heap (as it's the same heap address it could be the same bug). -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
