Crash Compiling Code::Blocks in Linux

[Ryu]

Hey, everybody.

From a revisions to here i have very much problems for compiling a new version.
The last in the current revision 2484 is the most extrange.

When the project is compiling the cbthreadpool.cpp he give a
internal compiler error !!(segmentation fault) maybe this is rigth and i
must send the bug to the compiler manteiners.
but how is the first time in all the programs that i compiled and is happend
to this version where you add this file i think i must tell you first.
so please tell me if this happend to other person for verify and change my compiler
version or give me a fix if you can.

thank you 

PD: I have gcc(g++) version 3.3.6 ; slackware 10.2 ; wxWidgets 2.6.2.

cbthreadpool.cpp has been there for quite a while now, even though I replaced it a few days ago, but that's no reason to produce an ICE (Internal Compiler Error).

I see your g++ version is a bit old. I'm pretty sure if you send a bug report it'll be marked as duplicated (which means it's already known).

Please try again with a newer version of gcc/g++ like 3.4.5 or 4.0.3. It should work just fine with any of those.

It crashes on Mac OS X 10.3 too, using GCC 3.3...
(it is not possible to upgrade the compiler there)

I got around it by using -O0 for this file (only),
as it won't compile (segfaults) with the usual -O2.

With the actual version from SVN the -O0 workaround does not work for my Mac (10.3.9, GCC 3.3).
But I found an other solution: remove -ffast-math switch and replace -O2 by -O0 in CXXFLAGS.

Code

$ man g++
...
       -ffast-math
...
           This option should never be turned on by any -O option since it can
           result in incorrect output for programs which depend on an exact
           implementation of IEEE or ISO rules/specifications for math func-
           tions.

Standard CXXFLAGS: -O2 -ffast-math
Maybe thats the reason for internal compiler error...

I am using Slackware 10.2 and can confirm the problem. The removal of -ffast-math and -O2 does not work for me

it works well for me on GCC 4.1.1

g++ -Wall -g `wx-config --cflags` -fmessage-length=0 -fexceptions -Winvalid-pch -fPIC -DcbDEBUG -DCB_PRECOMP -D__WXMAC__ -O0  -Isdk/wxscintilla/include -Isdk -Isdk/as/source -Isdk/as/include -Isdk/propgrid/include -Isdk/wxFlatNotebook -I/usr/include -Isdk -c sdk/cbthreadpool.cpp -o .objs/sdk/cbthreadpool.o

I cant get past this error. Even with -O0,

Here is the line from the .cbp. How do you put -O0 or turn off -ffast-math in it?
I can't find any -o2 or -ffast-math in the .cbp.

Code

		<Unit filename="sdk/cbthreadpool.cpp">
			<Option compilerVar="CPP" />
			<Option target="sdk" />

Edit: Is there a way to get back the older threadpool.cpp?

You want to change CXXFLAGS for C::B?
Try this when you compiling C::B:

./configure CXXFLAGS="-O0 -fno-fast-math"

No! if he wants just to compile it that was an option to make it. Of course you should never checkin this changes! But your configure option is better. I will delete the message above, just for security reason.
