This seems to have been an issue in libc, where running sin() with a specific value caused it to page fault. My current build of Wine did not report the full backtrace (I blame optimization levels), but using a binary wine build indeed produced the full backtrace. Resolved.
I gather the libc bug was fixed, correct?
Yes, that is correct. Simply upgrading to a -RC version of libc seems to have fixed it. I suspect a weird edge case of the specific libc version and the compiler version (as my gcc is the latest version, more recent than in my distros repos)
