[Bug 34813] New: winedbg crash reports are missing important information on Mac OS X 10.8+
http://bugs.winehq.org/show_bug.cgi?id=34813 Bug #: 34813 Summary: winedbg crash reports are missing important information on Mac OS X 10.8+ Product: Wine Version: unspecified Platform: x86 OS/Version: Mac OS X Status: NEW Severity: normal Priority: P2 Component: dbghelp AssignedTo: wine-bugs(a)winehq.org ReportedBy: ken(a)codeweavers.com Classification: Unclassified For an example, see attachment 46421 from bug 34811. Built-in DLLs are shown as PE modules instead of ELF wrappers around PE modules. The address ranges for the modules are likely incorrect. Many of them are shown as taking 4 pages (16KB) when I'm sure they're much larger. For example, gdi32. As a consequence, none of the stack frames resolve to symbols/functions. Few of them even resolve to modules other than "<wine-loader>". I believe this only affects OS X 10.8 and later. It doesn't affect 10.6.8. I suspect it has to do with image sliding. -- 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.

http://bugs.winehq.org/show_bug.cgi?id=34813 --- Comment #1 from Ken Thomases <ken(a)codeweavers.com> 2013-10-28 20:48:54 CDT --- The problem is Address Space Layout Randomization (ASLR). Dyld is being loaded into a random address in the process, which invalidates an assumption made in dlls/dbghelp/macho_module.c:macho_load_file(). That assumes that the address of the symbol "_dyld_all_image_infos" in /usr/lib/dyld is where the dynamic loader image info will be found in all processes. In the presence of ASLR, it's difficult to find where that dyld info really is. The only viable approach I've found is to use Mach's task_info() function with the TASK_DYLD_INFO flavor. This requires that the caller have the debuggee's Mach task port name. A task can obtain its own task port name, but to obtain the task port name of another task requires privileges. Wine processes do send their task port to the wineserver at startup, though. So, it would be possible for the debugger to request that the wineserver obtain the debuggee's dyld info and return it. (The TASK_DYLD_INFO flavor isn't declared in the 10.5 SDK, so we may need to keep the existing approach as a fallback until we abandon support for 10.5.) -- 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.
