--- Comment #8 from Gustavo Hime <gustavo.hime at mpimet dot mpg.de> --- > > I understand the issue. It isn't a problem with gfortran. > You do not understand the issue, which I made quite clear when reporting the bug. The code compiles, links and runs if no non-zero option is given to -finit-real. The code generator is probably doing something "silly" like attempting to fully unroll a loop of e.g. 2^30 iteration for initializing said array. It is a compiler bug because the compiler runs out of memory. God only knows how such a "silly" line of code, involving nothing but allocating static memory space and filling it with a repeated 8-byte constant, can cause a compiler to run out of memory. Probably not even He knows if this broken code cannot manifest itself in other situations, perhaps linked to other bugs, reported or not. Moreover, a memory allocation request is a safe operation. A program requests memory and may or may not get it from the OS. It is the program (i.e. compiler) responsibility to manage denied memory allocations. It is the programmers responsibility to make sure no unneeded memory is allocated. > > The compiler did not crash.

The compiler crashed because it terminated abnormally because it attempted to use more memory than the machine has without regard for systems limitations and, most important, without a good reason. The error message does not tell the programmer what caused the error in the program being compiled (there is none) nor what caused the compiler to exhaust system memory (which it had no reason for other than bad implementation). Are there any maintainers on the gfortran project who can see this? I am going to reopen the bug once more, but then I wash my hands. For the record, I'm not wasting my time reporting further bugs in gfortran if this is how the maintainers deal with the user community. I am one of the few who advocate gfortran in favour of the commercial alternatives at my institute, but you have seriously shaken my views just now.
