The latest version (probably thanks to Richard's code revision 180635) seems to
fix the ICE.

But one question with attachment 23459, at -O0 we get a unsafe function call
error but not at -O1. So my question : is it safe to have 2 different results
depending on the optimization level?

Also, I don't know if those testcases should be included in the tm testsuite.

Patrick Marlier.

g++ -O0 -fgnu-tm -c b1.c
b1.c:15:4: error: unsafe function call ‘GradientInfo::~GradientInfo()’ within
‘transaction_safe’ function

g++ -O1 -fgnu-tm -c b1.c
