g77 doesn't work perfectly on 64-bit configurations such as the Digital Semiconductor ("DEC") Alpha. What does a well diversified self-managed investment portfolio look like?

It seems that when crashing, the __result of function f somehow gets data address 0x0, which seems bit abnormal. assist. testsuite/ 2005-12-14 Erik Edelmann PR fortran/18197 * gfortran.dg/dummy_functions_1.f90: New.

Comment 7 eedelman 2005-12-06 19:38:49 UTC (In reply to comment #6) > Working on a patch. One possible cause of this problem is an unequal number of arguments in the argument list of a 'call' statement and the corresponding subroutine declaration as in: call foobar(x,y,z) <-- 3 I cant find any syntax > errors. This feature is considered to be absolutely vital, even though it is not standard-conforming, and is scheduled for version 0.6.

However, `2/10' cannot be represented by any finite number of sums of any of 1.0, 0.5, 0.25, and so on, so 0.2 cannot be exactly represented in binary notation.

Version 0.6 should solve most or all remaining problems (such as cross-compiling involving 64-bit machines). In my case, the error could have been caught by IMPLICIT NONE, or by run-time checking of string and array length.

The record length is of C type long; this means that it is 8 bytes on 64-bit systems such as Alpha GNU/Linux and 4 bytes on other systems, such as x86 And it turns out there's a similar bug for local equivalence areas, so that has been disabled as well.

AUTOMATIC would not, by itself, designate the containing procedure as recursive. As of Version 0.5.19, a temporary kludge solution is provided whereby some rudimentary information on a member is written as a string that is the member's value as a character string. It is possible for CPUs to support this, but this functionality is rarely required directly at the machine code level, thus CPU designers normally avoid implementing it and instead issue bus Wikipedia® is a registered trademark of the Wikimedia Foundation, Inc., a non-profit organization.

That is, these bugs can be quite sensitive to data, including data representing the placement of other data in memory (that is, pointers, such as the placement of stack frames in For example, a diagnostic would be produced for: PRINT 'HI THERE!' !User meant PRINT *, 'HI THERE!'

Part of the problem is the lack of detailed specifications regarding exactly how these options affect the interpretation of constants, intrinsics, and so on.

We know nothing about subroutine calrespknt. AUTOMATIC also would serve as a hint to the compiler that placing the variable or array--even a very large array--on the stack is acceptable. If a formatted WRITE produces an endless stream of spaces, check that your program is linked against the correct version of the C library. In particular, on systems other than those running the Linux kernel, the message might appear somewhat or very different, as it will if the error manifests itself while running a program

The call from main was a test line of code using a constant. Same with weirder things like construct names. Also, g77 should offer, perhaps even default to, warnings when characters beyond the last valid column are anything other than spaces. Generate a 6 character string from a 15 character alphabet A better way to evaluate a certain determinant Cyclically sort lists of mixed element types?

However, even with the improvements, these cases still require too much memory and CPU time. (Version 0.5.18 also improves cases where the initial values are zero to a much greater degree, Have g77 use a GBE construct similar to ADDR_EXPR but with extra information on the fact that the item pointed to won't be modified (a la const in C). i think something wrong with common block.

Why is water evaporated from the ocean not salty? Attempting to access a unit larger than a byte at an unaligned address can cause a bus error. A bus error occurs if the data sets passed during a main/subprogram to subprogram interface are not of equal size. For information on bugs that might afflict people who configure, port, build, and install g77, see 15.2 Problems Installing.

Some free tools are available which may help, specifically in Toolpack (which one would expect to be sound) and the `fortran' section of the Netlib repository.
