[Bug fortran/38437] New: truncation error in endfile
Hello, Ive got this problem * endfile: truncation failed in endfile apparent state: unit 1 named fort.1 last format: list io lately writing direct formatted external IO * On the file fort.1 I first open it, then read, then close, then write, then close again . But this happens randomly and even randomly with the 5 files I use in my program. The compiler is g77 for windows. On Linux it works perfectly (w/ gfortran). I really need to fix this problem, could you please suggest me what I should write inside my code to explain g77 that he should have a good behavior? :) Thanks Mario Alberto Annunziata -- Summary: truncation error in endfile Product: gcc Version: unknown Status: UNCONFIRMED Severity: critical Priority: P3 Component: fortran AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: marbertone at gmail dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38437
[Bug fortran/38467] New: gfortran builds programs which don't run on Vista
Hello,
I downloaded gfortran for windows in mingw32 edition. I try to compile a simple
program in fortran (test.f) and it goes ok. Also g77 compiles it, with the
difference that when I try to execute the program compiled with gfortran a
window appear: "Invalid win32 application", then i press ok and the program
stops, on cmd "forbidden access" appears. What should I do?
Thanks

I hope you give me some ideas! ;)

--- Comment #3 from marbertone at gmail dot com 2008-12-11 16:38 --- (In reply to comment #2) Hello, I attach you the problematic lines. Gfortran for windows doesn't work. It crashes in the two cases (native and cygwin). I repeat, on linux it works perfectly with gfortran. On Vista it says 'invalid win32 application after compiling'.

it works perfectly

the same as before. , a windows dialog box: "invalid Win32 application". It's a
true pity cause I need it to work on my laptop when I don't have internet
:(
