| Description: | ||||
The same build which produces a fully functional tcl using gcc also succeeds when using clang, but the resulting binary produces erratic results.
chan.test prints a lot of failures and eventually hangs. Random example:
==== chan-io-3.5 WriteChars: saved != 0 FAILED
==== Contents of test case:
# Bytes produced by UtfToExternal from end of last channel buffer had to
# be moved to beginning of next channel buffer to preserve requested
# buffersize.
set f [open $path(test1) w]
chan configure $f -encoding jis0208 -buffersize 17
chan puts -nonewline $f "\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"
set x [list [contents $path(test1)]]
chan close $f
lappend x [contents $path(test1)]
---- Result was:
!)!)!)!)!)!)!)!)! !)!)!)!)!)!)!)!)!!)!)!)!)!)!)!
---- Result should have been (exact matching):
!)!)!)!)!)!)!)!)! !)!)!)!)!)!)!)!)!)!)!)!)!)!)!)
==== chan-io-3.5 FAILED

Is the reporter is using LLVM Clang 13 or newer? If so, is this issue a duplicate of [24b9181478], i.e. fixed in Tcl 8.6.12? jan.nijtmans added on 2021-12-08 15:54:55:
Yes, this looks exactly like a duplicate of [24b9181478]. Closing. @dilfridge, if you still find this problem - somehow - in 8.6.12, please re-open this ticket. | ||||
