Sun Studio 12 ReleaseSolaris OS on x86 Platforms Kernel BugUnexpected SIGTRAP signal causes dbx debugger to hangWhen the dbx debugger is being used on the Solaris 10 OS on x86 platforms to debug a program that raises or delivers signals that have signal handlers, dbx might receive an unexpected SIGTRAP signal from the kernel that causes it to hang. This situation can occur when dbx is single stepping, running to a breakpoint, collecting runtime checking (RTC) data, or performing any other activity that depends on signal trapping. In some cases, dbx displays a warning of a unexpected SIGTRAP signal when it hangs; for example:
dbx: internal warning: unexpected SIGTRAP!In other cases, dbx indicates receipt of a SEGV signal, for example:
signal SEGV (no mapping at the fault address) in main at line 29 in file "test.c"Then when the user uses a cont -sig SEGV command to continue execution with the SEGV signal, dbx displays the warning of the unexpected SIGTRAP.
Workaround: This bug is introduced into Solaris 10 on x86 platforms when kernel patch 127112 is installed. Currently, the only workaround is to not install this kernel patch, or to uninstall it if it has been installed. As soon as a patch is available that fixes this bug, the patch information will be posted on this page. (May 19, 2008)
