| Summary | 0000960: Apache crashes on xdebug_start_code_coverage | ||||
| Description | Apache sometimes segfaults on my test servers for computing code coverage. According to gdb's backtrace, crash always occurs on a line with "xdebug_start_code_coverage". It seems like global variables previous_filename and previous_file are used before initialization in xdebug_code_coverage.c. It no longer crashes after I've added initialization to xdebug.c: + XG(previous_filename) = ""; + XG(previous_file) = NULL; | ||||
