| Summary | 0000549: Segmentation fault building stage 3 dependencies with GCC 9, -O6 and debug grades | ||||
| Description | Build staging 3 source file mappings or dependencies causes a segmentation fault when bootchecking in either of the grades asm_fast.gc.debug.stseg or asm_fast.gc.decldebug.stseg. This occurs (only) when compiling with -O6 (with and without --intermod-opt). Mercury: 22.01-beta-2022-02-16 C compiler: GCC 9.3.1 OS: CentOS 7 The issue did not occur with same optimisation settings and GCC 4.8.5 on the same machine. (I have GCC versions 10 and 11 installed on the same machine and will try them as well.) | ||||
