http://d.puremagic.com/issues/show_bug.cgi?id=9134 2013-03-01 08:40:55 PST --- I have a hunch that this might be because the function with the assert is called from a function with the extern (C) calling convention. Possibly, DMD tries to unwind the stack and fails when it gets to the function with the C calling convention... -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

I believe the problem might be that this assert is in a function that is indirectly called by a function with the extern (C) calling convention. The problem is further complicated because I call this function from x86 assembler code I wrote myself. I'm guessing the stack unwinding mechanism has a heart attack when it gets to that point in the stack. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------I ran into this bug as well.

http://d.puremagic.com/issues/show_bug.cgi?id=9134 ---OK. I can successfully run following code (with assertion failure, of course): import std.stdio; void main() { auto file = File("testcase.d","r"); foreach (ulong i, string line; lines(file)) assert(false); // Segmentation fault (core dumped) file.close(); } without any switches using githead. The fact that you are facing bug my be because it is already fixed in head. Can you test master branch? If there are no objections, I will close issue as WORKSFORME. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------DMD64 D Compiler v2.062 on Ubuntu 64 bit. assert (false); causes a segmentation fault.

http://d.puremagic.com/issues/show_bug.cgi?id=9134 PST --- It crashes only with Ubuntu Linux 12.10, dmd64. Under win32 it works fine. Interesting that even such code crashes with dmd64 2.062/linux and -release flag: void main() { assert(false); }It can be reproduced in any version with -release flag since assertion onconstant CT zero expression results in halt instruction. No. In win32 I have just an exception and in linux I have segmentation fault. Should I explain why is it unacceptable behavior? -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
