Does anyone have any idea why FreeBSD-3.2 did not trap Linux binaries which made a system call to linux_rt_sigprocmask() and why does FreeBSD-3.4 raise SIGSYS for the same call instead of letting it go unnoticed as before? One good example of a program with which I have seen this odd trap occurring is with Adobe FrameMaker for Linux. There are other programs of course, but this was the first one to come to my mind as an example. These are the three last lines of information produced by ktrace and linux_kdump. 59199 maker5X.exe CALL linux_rt_sigprocmask 59199 maker5X.exe PSIG SIGSYS SIG_DFL 59199 maker5X.exe NAMI "maker5X.exe.core" Any hints about known problems with Linux sigprocmask and potential workarounds would be most welcome.
