From 1db88d2272a776200db950c2af46e64e98ef056b Mon Sep 17 00:00:00 2001 From: Rainer Orth Date: Sun, 23 Sep 2018 19:49:14 +0200 Subject: [PATCH] Also recognize __sighndlr on Solaris/x86 Unlike Solaris/SPARC, the __sighndlr function isn't recognized as part of a signal handler, causing a couple of testcases to fail. The following patch fixes that. A followup patch will move this to common code to avoid such unnecessary discrepancies between Solaris/SPARC and x86 in the future. While this fixes a couple of backtraces to now correctly print #1 they often fail later with #2 0x0ff3ffffff00857f in ?? () Backtrace stopped: Cannot access memory at address 0xff3000002e0886f which needs further investigation.
