From: Reichelt <reichelt@igpm.rwth-aachen.de> To: gcc-gnats@gcc.gnu.org, gcc-bugs@gcc.gnu.org, georg@steffers.org Cc: Subject: Re: optimization/4490 Date: Mon, 8 Oct 2001 15:37:49 +0200 Hi, the problem can be reduced to the following testcase: void f() { unsigned long long ull; double d=ull; } I get a seg-fault when I try to compile this with "gcc -m128bit-long-double -c <filename>" using gcc 3.0 on an i686-pc-linux-gnu. The problem seems to be the cast from "unsigned long long" to "double" with "-m128bit-long-double" enabled (so it's probably not an optimization issue). In the original testcase this leads into trouble with the last "printf" statement in the function "compress". Greetings, Volker Reichelt http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view&pr=4490&database=gcc
