Valgrind && D

[Stefan Rohe]

Hi,

has anybody experience with the usage of valgrind and D?
We are here using DMD (dmd 1.033/tango 0.997 but also some older versions)
and got problems using valgrind on this.
It seems that the _d_newarrayT routine or something under it jumps or moves
on unitialized value(s).
Same with the _adDupT and _d_arrayappendT-method, which all call the
_D3gcx3Gcx11fullcollectMFPvZk method.
Has anybody the same experiences? Is it a bug within the Compiler or should
be something avoided?
