------- Comment #9 from fxcoudert at gcc dot gnu dot org 2007-03-17 18:45 ------- Created an attachment (id=13222) --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=13222&action=view) Proposed patch
I think the attached patch would fix this bug. It's a significant rewrite of the arith.c code to: * handle the case of large integer exponents for both complex and real; I do it by not extracting an int from the exponent, but simply handle the mpz_t throughout * rewrite completely the integer**integer case, because it had other problems, such as the following: $ cat c.f90 print *, 0**(-1) end $ gfortran c.f90 c.f90:0: internal compiler error: Floating point exception All testcases reported are fixed. I don't have any more time to work on this now, if one of you want to try the patch on the corner cases you can imagine, I'd appreciate that. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30834
