Timed Out After Longjmp

The parent is then supposed to signal the child to wake up again after it's done copying all these sections (heap, stack, etc.) The child needs a timeout for this wait, The CTRLC was coming from the UART. Would it be a solution to use pthread_kill to send the signal to a specific thread and then perform the longjmp ? –ssinfod Jul 7 '16 at 3:04 Longjmp In fact, setjmp/longjmp are generally implemented by saving the stack pointer so that restoring it makes sense only int the same execution context. check over here

This is not a bash bug, but a Windows limitations, and you are better off asking for help on the cygwin mailing list, not here, since there is nothing bash can At the end of the process, doxygen tries to run the html help compiler to create a .chm file, and that fails with the given error message: Generating graph info page... So yes it is astretch, but in my situation I could actually see it happen.I'll look into lightening the load on the system and give the doxygen alittle more processor time.Thanks Downloads release dev builds extras themes Documentation manual wiki device status Support forums mailing lists IRC Development bugs patches dev guide Search 1 Hour 1 Day 1 Week 1 Month Forever

  • What is confusing is that embedded MCUs typically don't have the standard library and no keyboard, so there is no ctrl-C.

It was on a Freescale MCU (16 bits) which contains a CodeWarrior C standard library. Only the different languages C and C++.

Sometimes after 20 or more hours of work bash exits as > it was killed with signal 9. But you mention c++ try and catch. Do we know exactly where Kirk will be born? I'm trying to have a similar behaviour while using threads (pthreads).

Preventing everything else. You can also look in '/var/log/setup.log.full' for diagnostic messages that were generated by 'setup.exe' the last time you ran it. You should try the latest cygwin DLL snapshot, and try rebasing (though I dunno if that would affect this or not.)

this message is different from time to > time but when it's printed it always has some mentioning of longjmp. You could instead get rid of your POSIX pthread, and use a timer signal activated with POSIX timer_create(). But bash is using longjmp correctly, so there is no bug to report on this list. - -- Life is short - so eat dessert first! Not the answer you're looking for?

Let's try to correct it. check my blog If you need further information, want me to try something and so on, please let me know. Yep, that's good. The idea is that I want either a timeout or a CTRL+C to restart an infinite loop.

These scripts do a lot of work and their normal execution time > is 20-40 hours. Why does the U-2 use a chase car when landing? So you'd consider sigsetjmp/siglongjmp. this content current community chat Stack Overflow Meta Stack Overflow your communities Sign up or log in to customize your list.

The parent was apparently still copying (in pass 3)when this happened, and so the copying failed with errno 5 (Accessdenied) as the child has terminated.The timeout is 5 minutes, and it's This will run the postinstall scripts, which seem to have not run the last time.

Previous by thread: Problems with bash+cygwin and longjmp Next by thread: Re: Problems with bash+cygwin and longjmp Index(es): Date Thread [email protected] Discussion: WFSO timed out after longjmp, data pass 3 failed Therefore if I can extend the timeout somewhat I hope Ican get rid of this.Disclaimer: There's a good chance that I'm way off base with thefollowing.WFSO stands for WaitForSingleObject and the Running html help compiler... have a peek at these guys But that's really a stretch.

Otherwise, I'd recommend running 'setup.exe' again and allow it to just run with the packages you have already selected. val = setjmp(env[ENV_TIMEOUT]); if (val!=0){ printf("[JMP TIMEOUT]\r\n"); } val = setjmp(env[ENV_CTRLC]); if (val!=0){ printf("[JMP CTRLC]\r\n"); } // main loop timeout_val = TIMEOUT_COUNT; i = 0; for (;;) { i++; if (i Index Nav: [DateIndex] [SubjectIndex] [AuthorIndex] [ThreadIndex] Message Nav: [DatePrev][DateNext] [ThreadPrev][ThreadNext] Other format: [Raw text] [BUG] (1.5.12-1) find(1) error message: "WFSO timed out after longjmp" From: Schneelocke But as this failure appears and as there were > periods when it happened often, we want to correct this behaviour very > much.
