SIGABRT in 22.locale.codecvt.out

• Key: STDCXX-790
• Type: Bug
• Status: Closed
• Resolution: Fixed

Description

Looks like a recent change to rw_printf() is causing 22.locale.codecvt.out.cpp to fail with SIGABRT. Here's the output of the test on HP aCC 6.16:

$ ./22.locale.codecvt.out -q
# ERROR (S8) (5 lines):
# TEXT: the environment variable TOPDIR is undefined
# CLAUSE: lib.locale.codecvt.virtuals
# FILE: locale.cpp
# LINE: 216

# ERROR (S8) (4 lines):
# TEXT: failed to create a locale database
# CLAUSE: lib.locale.codecvt.virtuals
# LINE: 670
