--- Comment #4 from Michael Stefaniuc mstefani@redhat.com 2013-06-04 15:21:00 CDT --- I've tested it too: The latest Realterm_2.0.0.70_setup.exe which was released on the day of this bug report crashes on 1.2, 1.4 as well as on wine-1.5.31-148-gf0806fd. wine: Unhandled exception 0x0eedfade in thread 9 at address 0x6f190937:0x7b83adf2 (thread 0009), starting debugger... err:seh:setup_exception_record stack overflow 816 bytes in thread 0009 eip 7bc75c45 esp 00241000 stack 0x240000-0x241000-0x340000
The previous version Realterm_2.0.0.57_setup.exe shows the same crashing behavior.
I have tested also Realterm_1-99-27.zip as the page still says: "Looking for the latest version? Download Realterm_1-99-27.zip (1.1 MB)". That does work on 1.2 but crashes in 1.4. That might be what the OP remembered when mentioning that it worked in the past. Anyway, that's not a regression in Wine as Realterm changed too.
