Possible illegal memory access due to uninitialized variable usage

[Parag2490]

Dear all,

 

We have come across a possible bug in the below API's code.

 

API	Varaible_name
zhbgvx	indibl
chbgvx	indibl
dsbgvx	indibl
ssbgvx	indibl
sstevx	indibl
dstevx	indibl
dspevx	indibl
chpevx	indibl
sspevx	indibl
zhpevx	indibl
chptrf	kpc
zhptrf	kpc
ssptrf	kpc
dsptrf	kpc
csptrf	kpc
zsptrf	kpc

 

 

Where variable is initialized only for particular condition and these variable are used for

Reading the data for unintalized index value.

 

Uninitialized could point to random locations in memory and create problems that memory might be used by some other program.

 

Example: In ssbgvx()

 

Here "indibl" variable is initialized after goto statement for condition.

@martin-frbg Is there anything else that needs to be done or can this issue be closed?

My earlier PR fixed the clear cases of uninitialized accesses. My impression with the remaining ones was that the compiler warnings are spurious, but I had intended to double-check "later".
