| Summary | 0022595: gp_Mat's constructors incompletely initilize memory | ||||
| Description | RLN_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. | ||||
