Crash bug in master from a few minutes ago

[rockn]

Yes, I'm seeing the same.
It look like it's since git commit 8219102

Thanks Jim, I was trying to make a clear post on that but was too slow to write it

[sgrogan]

I think Line 71 and 72 of CMakeLists.txt form Rockn's link should be

Code: Select all

    ENDIF(GCC_VERSION VERSION_GREATER 4.7 OR GCC_VERSION VERSION_EQUAL 4.7)
ENDIF(CMAKE_COMPILER_IS_GNUCXX)

I'm compiling master on Travis-CI (No linux here) if the self tests catch the error I'll try the potential fix.
EDIT:Unit tests don't catch the error on Travis-CI so I can't test the potential fix now.
EDIT2:See Here https://github.com/FreeCAD/FreeCAD/pull/83

[sgrogan]

OK, I think I got it
Potential patch forthcoming.

[ian.rees]

In case this isn't what sgrogan found: I think there's a bug at src/App/DocumentObject.cpp line 275 - the boost::any constructor essentially runs off into an infinite loop when -std=c++11 is enabled [edit: *on an essentially stock Ubuntu 14.04]. -Ian-

[sgrogan]

n case this isn't what sgrogan found:

No this isn't and as it turns out I got exicited a little to early

[yorik]

[edit: *on an essentially stock Ubuntu 14.04]. -Ian-

Apparently yes. For me everything seems to run fine (debian testing: gcc 5.3.1 + boost 1.58)

[rockn]

On Ubuntu 14.04 :
boost 1.54
gcc 4.8

[ian.rees]

There's a bug in boost 1.54 (fixed in 1.55 http://lists.boost.org/Archives/boost/2 ... 206955.php ) which is the cause of this crash. I've made a super quick attempt at a fix, not sure if it found all cases: https://github.com/ianrrees/FreeCAD_tin ... workaround -Ian-

[rockn]

Hi Ian,

It compile and run fine with your fix.

Thanks.
