------- Comment #3 from sliwa at cft dot edu dot pl 2007-08-06 12:41 ------- 1. The attached d1mach.f works fine with g77. 2. The numbers are 32-bit, so why an overflow? Maybe the number is extended as a signed number (padded with ones), and the conversion is unsigned. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33001
