Bug#572774: /usr/bin/iconv: assert failed - iconv: malloc.c:3096: sYSMALLOc: Assertion

[Sergey Burladyan <eshkinkot@gmail.com>]

Package: libc-bin
Version: 2.10.2-6
Severity: minor
File: /usr/bin/iconv


When i have mistake in writing (//IGNORE - //INGORE) and my locale is not C or POSIX, then iconv generate assert:

$ dd if=/dev/zero bs=4M count=1 | iconv -f cp1251 -t utf8//INGORE > /dev/null
iconv: malloc.c:3096: sYSMALLOc: Assertion `(old_top == (((mbinptr) (((char *) &((av)->bins[((1) - 1) * 2])) - __builtin_offsetof (struct malloc_chunk, fd)))) && old_size == 0) || ((unsigned long) (old_size) >= (unsigned long)((((__builtin_offsetof (struct malloc_chunk, fd_nextsize))+((2 * (sizeof(size_t))) - 1)) & ~((2 * (sizeof(size_t))) - 1))) && ((old_top)->size & 0x1) && ((unsigned long)old_end & pagemask) == 0)' failed.
Аварийный останов

correct spelling:
