[Rivet] Problem with AGILe and FHerwig

[Adam Davison]

Hi,

I've been trying to set up and run FORTRAN Herwig via AGILe on a 64-bit 
Intel Macbook.

Every time I run agile-runmc Herwig:6.510 I get a crash with an error like:

AGILe.Loader: TRACE  Successfully loaded 
/Users/adamd/local/x86_64/build/genser/herwig/6.510.2/x86_64-Darwin-gcc42-opt/lib/libherwig_dummy.dylib 
(0x1002d4770)
python(58746) malloc: *** error for object 0x7fff70bb0500: pointer being 
freed was not allocated

I dug into the code and with the aid of some printfs determined that 
agile is causing this malloc fault in FHerwig::FHerwig() on, of all 
things, this line:

     _particleNames[ELECTRON]    = "E-      ";

Now that seemed rather strange, I tried some stuff, and in the end I get 
to the point where I have inserted this code above that crash:

         std::map<int, std::string> b;
//      b[1] = std::string("hi");
         b[2] = std::string("hi2");

Uncommenting the middle line, causes agile-runmc to crash on the second 
line. All of this makes me think there's some kind of memory corruption, 
probably heap, given the fact that it's a malloc error ultimately.

Does anyone have any ideas what could be going wrong here?

I'm using gcc4.2 from the Apple developer tools, let me know if anything 
else would help.

Thanks, any help much appreciated,

Adam
