Freeze While Parsing Prelude

On my system (Gentoo Linux PPC, GCC 2.95.3), Hugs goes into an infinite loop while parsing the Prelude file. The problem is in input.c, lines 515 and 516: lineBuffer[lineLength] = fgetc(inputStream); if (lineBuffer[lineLength] == EOF) The value of EOF cannot be stored in a char on this system, so 'lineBuffer[lineLength] == EOF' always evaluates to 0. Here's a fix: int ch = fgetc(inputStream); lineBuffer[lineLength] = ch; if (ch == EOF) Glad to help, Jeff Binder
