[-- Attachment #1 --] Hello, I compiled ghostscript 5.5 from the ports collection. When I run this program it immediately crashes with a floating point exception. I have a Cyrix 486DX and the kernel detects npx0 while booting. So, I have a FPU. Gs gets the signal in png_push_fill_buffer() which is an empty function in gdevpnm.c. I don't understand how a FPU exception can occure in an empty function. Does somebody know how to solve this? I attached a backtrace of gdb and the output of truss. -- Ronald Klop http://node11a94.a2000.nl/~ronald/ [-- Attachment #2 --] gdb gs GNU gdb 4.18 Copyright 1998 Free Software Foundation, Inc.
