The cvs log file for newlib sys/reent.h is so big for the last months
that even if the line of code has not changed, what it does has indeed
changed. And bizarely it as changed much between 1.10 and 1.11 and even
post that. Besides the macro itself has changed and the code now looks
like :
*ptr = {0, & (*ptr).__sf[0], ...};
which I do not even understand it compiles or its exact meaning. Now
that there is a macro for using pointers (added in april 2002), I think
it is more reasonnable to use it and indeed it cures the problem. I do
not want to disassemble the code to see exactly what is wrong but I
guess it at least corrupt the stack by allocating a temporary struct
reent on it and copying a block of stack in an undefined state
especially if irq are on...
Feel free to compare the two generated code :-)
