Summary0022595: gp_Mat's constructors incompletely initilize memory
DescriptionRLN_fix435
- Summary: gp_Mat's constructors incompletely initilize memory when compiled by
gcc 4.1.2 with -O2
- Detailed description: gp_Mat constructors use indirect memory reference
((Standard_Real*)&matrix[0][0])[i]) to access elements of the member field
matrix[3][3]. Likely due to gcc bug this results in uninitialized memory and
further crashes when using that garbage. See details at
http://www.opencascade.org/org/forum/thread_19603/.
gp_XYZ.lxx had to be fixed as well since it used the same macros defined in
gp_Mat.lxx. Macros in gp_Mat.lxx could be removed too to avoid possible
conflicts with user's code but currently left to minimize modifications.
TagsNo tags attached.
