[Bug fortran/54405] New: bad debugging info which lead to a wrong behavior of reverse-next in gdb
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54405 Bug #: 54405 Summary: bad debugging info which lead to a wrong behavior of reverse-next in gdb Classification: Unclassified Product: gcc Version: 4.6.3 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran AssignedTo: unassig...@gcc.gnu.org ReportedBy: edouard.ca...@irisa.fr Created attachment 28098 -- http://gcc.gnu.org/bugzilla/attachment.cgi?id=28098 short fortran source file used in the example Reverse debugging works badly with the attached fortran source file, at least when using GCC 4.6.3 and GCC 4.7.1. More precisely, during debugging, the first use of the 'reverse-next' command (after using record, of course), makes the debugger jump back the first line where the 'record' command was applied; for example: === (gdb) break MAIN__ Breakpoint 1 at 0x402f87: file essai_1.f90, line 3. (gdb) run Starting program: .../essai_1 Breakpoint 1, essai_1 () at essai_1.f90:3 3 x = 1.0 (gdb) record (gdb) n 4 print *, x = , x (gdb) n x =1. 6 x = 2.5 (gdb) n 7 print *, x = , x (gdb) n x =2.5000 9 x = 3.14159265 (gdb) n 10 print *, x = , x (gdb) n x =3.14159274 12end program (gdb) reverse-next 4 print *, x = , x == The behavior is correct with GCC 4.5.4, so I think it is a regression problem. The problem has been detected with gdb-7.4 and gdb-7.5.
[Bug fortran/52788] New: -fbounds-check fails for 2-rank allocatable arrays when reading
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52788 Bug #: 52788 Summary: -fbounds-check fails for 2-rank allocatable arrays when reading Classification: Unclassified Product: gcc Version: 4.7.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran AssignedTo: unassig...@gcc.gnu.org ReportedBy: edouard.ca...@irisa.fr For the following code: program test1 implicit none double precision, allocatable :: C(:,:) integer :: i allocate( C(3,2) ) open(10,file='C.dat') do i = 1, 4 read(10,*) C(i,:) ! fbounds-check doesn't work end do close(10) end program gfortran doesn't catch at run-time the last data read using the first dimension i=4 The data file 'C.dat' is not important, I have used: $ cat C.dat 1.0 -1.0 2.0 -2.0 3.0 -3.0 4.0 -4.0 but it can contains any numerical data spread over two columns. --- The previous code has been compiled with: $ gfortran -fbounds-check -o test1 test1.f90 The failure occurs at least for the following version of gcc: 4.3.6, 4.4.7, 4.5.3, 4.6.3, 4.7.0 i.e. all known versions from 4.3

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52788 --- Comment #1 from Edouard.Canot at irisa dot fr 2012-03-30 07:11:41 UTC --- For a one dimensional allocatable array, gfortran leads to a correct behavior when reading, i.e. it detects the bounds overflow.
