Commit 8418552 ("[klibc] ia64: Fix shared build") missed this use of the GP register, although the code appears to have been dubious anyway, assuming the address of errno was the first thing pointed to by GP. --- usr/klibc/arch/ia64/vfork.S | 6 +----- 1 file changed, 1 insertion(+), 5 deletions(-) diff --git a/usr/klibc/arch/ia64/vfork.S b/usr/klibc/arch/ia64/vfork.S index

Patch registers SIGTSTP hook where it sends reset terminal color control sequence using write and fsync. Handler is installed only if signal is not being ignored. Patch uses rl_free_line_state and rl_cleanup_after_signal to unhook readline from terminal, then it calls original TSTP handler using approach in URL below and again hooks readline using rl_reset_after_signal. Handling is based on code

Hello, I've been trying to get openssh working at our site recently, but have been running into these problems. In using the "release" version (openssh-2.3.0p1) we kept getting these broken pipe errors: zcat: stdout: Broken pipe Damien suggested we try out the snapshot versions, so I've been trying out the daily versions since last week. With the snapshots, the pipe problem
