[Mono-dev] Process.GetCurrentProcess().Modules crashes on Mac OS X Snow Leopard

[Tom Philpot]

Since Romain¹s fix didn¹t seem to fix the issue, I did some digging today.
This seems to fix the issue sufficiently for us on Snow Leopard.

Apparently not all dylibs on Snow Leopard have a __data section. For example
Cocoa on Snow Leopard does not, but Cocoa on Leopard does.

otool -l /System/Library/Frameworks/Cocoa.framework/Versions/Current/Cocoa |
grep __data

Please have at the attached patch and see if there are any issues.

Thanks,
