[Bug 37248] New: Floating point stack fault in a program compiled with Silverfrost FTN95
https://bugs.winehq.org/show_bug.cgi?id=37248 Bug ID: 37248 Summary: Floating point stack fault in a program compiled with Silverfrost FTN95 Product: Wine Version: 1.7.25 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: pepalogik(a)seznam.cz I use Silverfrost FTN95 compiler <http://www.silverfrost.com/11/ftn95/ftn95_fortran_95_for_windows.aspx> for debugging a Fortran 77 code. This compiler has quite a unique CHECKMATE feature which performs various run-time checks, but this compiler is Windows-only. First it seemed to work fine in Wine but then, when I used a larger code, the program execution resulted in a floating point stack fault. Note that the compiler itself works correctly in Wine, but the resulting CHECKMATE-enabled executable fails (while the very same executable runs well on Windows). I was happy when I found a workaround: to compile the program with /F_STDCALL. Unfortunately, this turned out to be insufficient for an even larger code (it is actually the same program with just larger parameter values and thus larger arrays and more iterations in various cycles). For this code, /F_STDCALL only causes the floating point stack fault to occur later. I cannot 100% guarantee that the code is correct - a floating point stack fault can be caused e.g. by calling a function with an incorrectly specified return type. However, I think this is unlikely for the following reasons: 1. It does work on MS Windows, 2. It has been checked with two different compilers (FTN95 and gfortran). 3. It has been checked with Silverfrost's CHECKMATE run-time checking (as it runs on Windows without failure). 4. It has been checked by me. Hence I guess it is a bug in Wine. What files do you need to tackle this problem? As the executable needs a Silverfrost's runtime library, you will have to install FTN95 in any case. I suggest that I will upload these files and information: * program source, * compiling instructions, * input files (which are required by the program). I will now wait for either your response or the appearance of Wine 1.7.26 in the PPA (it seems to be to complicated for me to build it from the source). If the latter happens earlier, I will check if the bug persists and upload the files I have suggested. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=37248 --- Comment #3 from Jan Lachnitt <pepalogik(a)seznam.cz> --- So here it is. INSTRUCTIONS: Install FTN95 in Wine in 32-bit mode (i.e. WINEARCH=win32). I use 32-bit mode by default because some applications do not work in 64-bit mode. Then unpack wine-FTN95-crash-full.zip to an empty directory and cd to that directory in a terminal. Now build the program with the build script... wineconsole build.bat ... and launch the program. wine satleed1.exe It crashes with a floating point stack fault at energy 38 eV. Optionally, you can also retry with the /F_STDCALL flag activated. This is a workaround that helps sometimes but not for this program. wineconsole build_with_F_STDCALL.bat Before re-launching the program, it is necessary to delete old output files. rm tleed.o short.t Now you can start the program again. wine satleed1.exe Having been compiled with /F_STDCALL, it crashes somewhat later (at energy 39 eV). VERIFICATION ON WINDOWS: If you build and run the program on Windows, it does not crash (whether it has been compiled with or without /F_STDCALL). It does not matter whether you build the program on Windows or Linux with Wine. You can copy the files "satleed1.exe", "tleed4.i" and "tleed5.i" from one OS to the other and just launch "satleed1.exe" (the other two files are input files), so that you do not have to rebuild the program on the other OS. However, you always have to install FTN95 first as the executable uses its runtime library. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
