Hello,
my bash-3.2.48 (uses readline-6.2) on AIX computer produces stange errors,
that I could trace back:
SIGWINCH->
signals.c:rl_sigwinch_handler ->
terminal.c:rl_resize_terminal ->
terminal.c:_rl_get_screen_size ->
shell.c:sh_set_lines_and_columns ->
libc:setenc ->
libc:putenv ->
libc: realloc
And finally realloc overwrites an unrelated data area (bash's
variables.c:export_env),
which causes bash to get SIGSEGV
My documentations suggest that one shouldn't call (directly or
indirectly) malloc/free/realloc from signal handler,
so I think there should be a way to let these setenv/putenv calls to be
delayed until the next readline-operation.
Yours: Lőrinczy Zsigmond
