--- Comment #3 from P dot Schaffnit at access dot rwth-aachen dot de 2006-05-03 11:44 --- Hi! I believe this could be related: compiling the following with any optimisation (starting from -O1) causes the following error: initFeldVonDatei.f90: In function 'initfeldvondateiphase2korn': initFeldVonDatei.f90:1: internal compiler error: in n_of_executions_at_most, at tree-ssa-loop-niter.c:1772 Please submit a full bug report, with preprocessed source if appropriate. See URL:http://gcc.gnu.org/bugs.html for instructions. Shall I file a bug? Am I doing something wrong? Thanks! Philippe PS: the build command I'm using: gfortran -O1 -c Sources.f90 PPS: the source SUBROUTINE initFeldVonDateiPhase2Korn !

--- Comment #4 from kargl at gcc dot gnu dot org 2006-05-03 17:10 --- Phillipe, Your code appears to be wrong, or perhaps you've cut down a larger code too agressively. You use the Fortran ALL intrinsic on the allocatable NEW_NUMBER, but you have never actually allocated memory for the array. -- steve -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27392

--- Comment #5 from P dot Schaffnit at access dot rwth-aachen dot de 2006-05-03 19:28 --- Erm... sorry about that, I didn't think about it: I've indeed thrown out a lot (I do not have the original sources at hand, but they are happily compiled by quite a few compilers, including lf95, as far as I can tell, is a reference...): anyway, I thought that the mere fact that *any* code causes an ICE is bad, I hoped this could help, I'll try to reduce it a bit less aggressively tomorrow...
