Bug ID: 96664
Summary: ICE on SPARC v9 with UBSan
Product: gcc
Version: 10.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: sanitizer
Assignee: unassigned at gcc dot gnu.org
Reporter: robb at datalogics dot com
CC: dodji at gcc dot gnu.org, dvyukov at gcc dot gnu.org,
jakub at gcc dot gnu.org, kcc at gcc dot gnu.org, marxin at
gcc dot gnu.org
Target Milestone: ---
We build our prop library with gcc-9.2 on SPARC Solaris 11.3, where I first
found that UBSan builds generate an ICE.
So to determine if this problem was fixed before reporting the bug, I built
gcc-10.2.0 but found the same result. Unfortunately I cannot provide
preprocessed source for this case, as our licensing agreement precludes that
explicitly, but I can rebuild gcc from a git branch and provide any other
feedback that might be helpful.
