| Summary | 0025078: Coding rules - eliminate GCC warning -Wclobbered | ||||
| Description | A lot of new clobbering warnings as of 6.7.1, I think. Possible the behavior may be intentional.

Branch CR25078 has been created by abv. SHA-1: e59e20650bd56a5ebff74029b7d8d3c89201158d Detailed log of new commits: Author: abv Date: Sun Nov 8 20:17:47 2015 +0300 0025078: Coding rules - eliminate GCC warning -Wclobbered GCC warning -Wclobbered suppressed in Standard_ErrorHandler.hxx when OCC_CONVERT_SIGNALS or NO_CXX_EXCEPTIONS are used |
|
|
This warning appears on Linux with GCC wherever OCC_CATCH_SIGNALS macro is used (usually inside try/catch block). Its purpose is to translate C system signals to C++ exceptions (it defines a landing point for longjump to return from C signal handler). The warning applies to local variables constructed before OCC_CATCH_SIGNALS and indicates that their value may be not as expected when jump occurs. The right way to solve this issue is to avoid having any local variables in the code of the function where OCC_CATCH_SIGNALS macro is used, declared before that macro. This is possible, but requires completely different approach to using this macro. Current approach is to add it in the place where exception is to be caught, i.e. in the try {} block, and idea behind this is that this will enable this try {} to handle C signals. Correct approach would be to use it instead in the functions that can cause signal. The problem is that when function / place where signal can be generated is known, it is more logical to avoid this situation at all, instead of relying on signal processing. That is, it seems not practical trying to revise existing implementation, and these warnings should be just ignored. The patch implements this, please review. |
