During normal compilation of Mesa git i get the below. Worked before latest gcc update (compiled Mesa git last on June, 25). gcc (SUSE Linux) 10.1.1 20200625 [revision c91e43e9363bd119a695d64505f96539fa451bf2] mkdir build cd build meson ../ --strip --buildtype release -Ddri-drivers= -Dplatforms=drm,x11 -Dgallium-drivers=r600,radeonsi,swrast -Dvulkan-drivers=amd -Dgallium-nine=true -Dopencl-spirv=true -Dgallium-opencl=standalone -Dglvnd=true -Dgallium-va=true -Dgallium-xvmc=false -Dgallium-omx=disabled -Dgallium-xa=false It works without 'swrast' (softpipe) but I do NEED it for 'nine', so I have to disable 'nine' (delete '-Dgallium-nine=true') to get some things for testing. ../src/gallium/drivers/softpipe/sp_quad_blend.c:247:46: warning: ‘res[3][2]’ may be used uninitialized in this function [-Wmaybe-uninitialized] 247 | quadColor[j][2] = ubyte_to_float(res[j][2]); | ~~~~~~^~~ ../src/gallium/drivers/softpipe/sp_quad_blend.c:248:46: warning: ‘res[3][3]’ may be used uninitialized in this function [-Wmaybe-uninitialized] 248 | quadColor[j][3] = ubyte_to_float(res[j][3]); | ~~~~~~^~~ [1140/1479] Compiling C object 'src/gallium/driv...oftpipe/48c2f4b@@softpipe@sta/sp_tex_sample.c.o' FAILED: src/gallium/drivers/softpipe/48c2f4b@@softpipe@sta/sp_tex_sample.c.o ccache cc -Isrc/gallium/drivers/softpipe/48c2f4b@@softpipe@sta -Isrc/gallium/drivers/softpipe -I../src/gallium/drivers/softpipe -Isrc/gallium/auxiliary -I../src/gallium/auxiliary -I../src/gallium/include -Iinclude -I../include -Isrc -I../src -fvisibility=hidden -fdiagnostics-color=always -DNDEBUG -pipe -D_FILE_OFFSET_BITS=64 -Wall -Winvalid-pch -std=c99 -O3 -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS '-DPACKAGE_VERSION="20.2.0-devel"' '-DPACKAGE_BUGREPORT="https://gitlab.freedesktop.org/mesa/mesa/-/issues"' -DUSE_ELF_TLS -DHAVE_ST_VDPAU -DENABLE_ST_OMX_BELLAGIO=0 -DENABLE_ST_OMX_TIZONIA=0 -DHAVE_X11_PLATFORM -DGLX_INDIRECT_RENDERING -DGLX_DIRECT_RENDERING -DGLX_USE_DRM -DHAVE_DRM_PLATFORM -DENABLE_SHADER_CACHE -DHAVE___BUILTIN_BSWAP32 -DHAVE___BUILTIN_BSWAP64 -DHAVE___BUILTIN_CLZ -DHAVE___BUILTIN_CLZLL -DHAVE___BUILTIN_CTZ -DHAVE___BUILTIN_EXPECT -DHAVE___BUILTIN_FFS -DHAVE___BUILTIN_FFSLL -DHAVE___BUILTIN_POPCOUNT -DHAVE___BUILTIN_POPCOUNTLL -DHAVE___BUILTIN_UNREACHABLE -DHAVE_FUNC_ATTRIBUTE_CONST -DHAVE_FUNC_ATTRIBUTE_FLATTEN -DHAVE_FUNC_ATTRIBUTE_MALLOC -DHAVE_FUNC_ATTRIBUTE_PURE -DHAVE_FUNC_ATTRIBUTE_UNUSED -DHAVE_FUNC_ATTRIBUTE_WARN_UNUSED_RESULT -DHAVE_FUNC_ATTRIBUTE_WEAK -DHAVE_FUNC_ATTRIBUTE_FORMAT -DHAVE_FUNC_ATTRIBUTE_PACKED -DHAVE_FUNC_ATTRIBUTE_RETURNS_NONNULL -DHAVE_FUNC_ATTRIBUTE_ALIAS -DHAVE_FUNC_ATTRIBUTE_NORETURN -DHAVE_FUNC_ATTRIBUTE_VISIBILITY -DHAVE_UINT128 -D_GNU_SOURCE -DUSE_SSE41 -DUSE_GCC_ATOMIC_BUILTINS -DUSE_X86_64_ASM -DMAJOR_IN_SYSMACROS -DHAVE_LINUX_FUTEX_H -DHAVE_ENDIAN_H -DHAVE_DLFCN_H -DHAVE_EXECINFO_H -DHAVE_SYS_SHM_H -DHAVE_CET_H -DHAVE_STRTOF -DHAVE_MKOSTEMP -DHAVE_TIMESPEC_GET -DHAVE_MEMFD_CREATE -DHAVE_RANDOM_R -DHAVE_FLOCK -DHAVE_STRTOK_R -DHAVE_GETRANDOM -DHAVE_PROGRAM_INVOCATION_NAME -DHAVE_POSIX_MEMALIGN -DHAVE_DIRENT_D_TYPE -DHAVE_STRTOD_L -DHAVE_DLADDR -DHAVE_DL_ITERATE_PHDR -DHAVE_ZLIB -DHAVE_ZSTD -DHAVE_PTHREAD -DHAVE_PTHREAD_SETAFFINITY -DHAVE_LIBDRM -DLLVM_AVAILABLE '-DMESA_LLVM_VERSION_STRING="11.0.0"' -DUSE_LIBGLVND=1 -DHAVE_LIBUNWIND -DHAVE_DRI3 -DHAVE_DRI3_MODIFIERS -DHAVE_LIBSENSORS=1 -Werror=implicit-function-declaration -Werror=missing-prototypes -Werror=return-type -Werror=empty-body -Werror=incompatible-pointer-types -Werror=int-conversion -Wimplicit-fallthrough -Wno-missing-field-initializers -Wno-format-truncation -fno-math-errno -fno-trapping-math -fno-common -Werror=format -Wformat-security -fPIC -Werror=pointer-arith -Werror=vla -MD -MQ 'src/gallium/drivers/softpipe/48c2f4b@@softpipe@sta/sp_tex_sample.c.o' -MF 'src/gallium/drivers/softpipe/48c2f4b@@softpipe@sta/sp_tex_sample.c.o.d' -o 'src/gallium/drivers/softpipe/48c2f4b@@softpipe@sta/sp_tex_sample.c.o' -c ../src/gallium/drivers/softpipe/sp_tex_sample.c during IPA pass: fnsummary ../src/gallium/drivers/softpipe/sp_tex_sample.c: In function ‘sample_compare’: ../src/gallium/drivers/softpipe/sp_tex_sample.c:3862:1: internal compiler error: Segmentation fault 3862 | } | ^ Please submit a full bug report, with preprocessed source if appropriate.
