2001-10-05Wohoo! David McCullough found the bug! His comments follow:Eric Andersen
I had a look at it and you won't believe it was always broken. I'll try and explain it, let me know if it doesn't make sense. * ash calls setjmp, which messes with the stack to look like it has two args instead of one and then jmps (actually falls) into sigsetjmp. BUG * sigsetjmp then saves the registers and "jumps" to __sigset_save, a C function. BUG1 - because the caller pops its args off the stack, a program that changes it's number of args is broken because the caller will not pop the correct number of args. I think that jumping from the sigsetjmp asm to the 'C' code is unsafe but I can't think of an example. Anyway, I have attached what I think is a working fix. The reason this worked without -fomit-frame-pointer is that the _sigset_save 'C' code would restore the stack pointer from %ebp (the frame pointer) and because none of the asm had moded it, when we returned from __sigset_save the stack was back to it's correct position for 1 argument despite our best attempts to stuff it up ;-)

2001-10-04Patch from David McCullough <davidm@lineo.com>:Eric Andersen
* reduce the sigset types to 32 bits (I've mentioned this before) I think I saw this change go in for another platform anyway ;-) * Do not use _IO_FILE as it clashes with the C++ libraries which know too much about how glibc workds :-( * Do not use _G_va_list for the same reason. * remove the CTORS/DTORS from crt0.S for ARM as the compiler provided crtbegin.o and crtend.o have these (and only these) already in them and you get multiple defined errs :-(

2001-08-30"Kim B. Heino" <Kim.Heino@bluegiga.com> reportsEric Andersen
In the libc/stdlib/bsd_getpt.c file you have line: memcpy (buf, _PATH_PTY, sizeof (_PATH_PTY) - 1); It really should be: memcpy (buf, _PATH_PTY, sizeof (_PATH_PTY) ); The last nul character must be copied too because the next line uses strlen() to get buf's length.
