Bug 893408 – media-libs/zvbi-0.2.35-r2: fails to compile with non standard compiler flags (error: inlining failed in call to 'always_inline' 'open.localalias': function not inlinable)

• Status: UNCONFIRMED
• Product: Gentoo Linux

[Description dani-g5x 2023-02-06 15:51:32 UTC]

the package fails to compile when this compiler flags are used:
NTHREADS="auto"

source /etc/portage/make.conf.lto.defines

COMMON_FLAGS="-march=native -O3 ${GRAPHITE} ${SEMINTERPOS} ${IPA} ${FLTO} ${IPAPTA} ${DEVIRTLTO} ${SAFEST_FAST_MATH} -fuse-linker-plugin -falign-functions=32 -pipe"

CPU_FLAGS_X86="aes avx avx2 f16c fma3 mmx mmxext pclmul popcnt rdrand sse sse2 sse3 sse4_1 sse4_2 ssse3"

CFLAGS="${COMMON_FLAGS}"
CXXFLAGS="${COMMON_FLAGS}"
CFLAGS="${COMMON_FLAGS}"
FFLAGS="${COMMON_FLAGS}"


Reproducible: Always

Steps to Reproduce:
1.utilize specified compiler flags
2. emerge media-libs/zvbi

Actual Results:  
package fails to compile.

Expected Results:  
package should be installed correctly with user specified compiler flags.

Please try narrow down which flag causes it.

I will try, there a lot of flags to test with so it could take a while

I, also, encountered this error. Not using exactly same flags, but without -fno-semantic-interposition zvbi compile fine with lto.
Maybe, is this gcc bug: 
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101270 ?
