I guess it's fixed in trunk by something in
90e46074e6b3561ae7d8ebd205127f286cc0c6b6:
@@ -166,9 +158,10 @@ bool SupportsColoredOutput(fd_t fd) {
#if !SANITIZER_GO
// TODO(glider): different tools may require different altstack size.
static uptr GetAltStackSize() {
- // SIGSTKSZ is not enough.
- static const uptr kAltStackSize = SIGSTKSZ * 4;
- return kAltStackSize;
+ // Note: since GLIBC_2.31, SIGSTKSZ may be a function call, so this may be
+ // more costly that you think. However GetAltStackSize is only call 2-3
times

+ return SIGSTKSZ * 4;
}
Not tested though.
