--- Comment #3 from Sebastian Lackner sebastian@fds-team.de --- The procedure used to find the regression commits sounds a bit unusual. Is ca51e113e4820f8b11016c13732b1a971d2b0054 really the first commit with which the application crashes?
Some of the commits you had to revert to get it working on 1.7.34 look totally unrelated, and suggest that it is kinda random, and probably a stack related issue (uninitialized values on the stack or stack corruption). Maybe even also a copy-protection check which depends on specific assembler output for some functions.
