Hi
This is a weird issue, and I'm by no means sure that my description is
correct. It might be a newbie misunderstanding, but it is weird
behaviour and I would appreciate any help in getting to the bottom of
it.
Here is a minimal example that exhibits the issue: ("zeromain.cpp")
#include
#include
int main (int argc, char * argv[])
{
boost::numeric::ublas::coordinate_matrix<double> cm;
cm.resize(3,3, false);
return 0;
}
When compiled [with bjam release] and linked to libboost_thread it
gives a "bus error". The backtrace is appended to this email. It
works fine in debug mode.
You can see that I have introduced boost.thread but not yet actually
used the thread library in any way. If I take out either the include,
or don't link to the lib, the bug goes away.
Thanks in advance for any help or suggestions! Details below.

The boost libraries are in $DYLD_LIBRARY_PATH.
Jamroot contains

It is a regular build of the boost libraries.)
