[PATCH] PR 30460: asm_debug is not initialized in gcc.c

Reply-to: Robert Schiele <rschiele at gmail dot com>

Hi there!

Please apply the following patch at least to 4.3, 4.2, and 4.1 because they
all have asm_debug uninitialized possibly leading to a SIGSEGV when providing
a custom specs file.  I have not checked older releases than the 4.1 tree but
most likely they suffer from the same problem.
